Crimson High
A downloadable game for Windows, macOS, Linux, and Android
When Ren (or whatever you decide to call him) is assigned to investigate a murder at Crimson High, he expects to face some challenges. However, he soon realizes that the school's secrets are far more complex than he could have ever imagined. And with a cast of quirky characters, including some adorable girls, Ren's adventure was only just beginning.
Join him on his quest to solve a murder case and find himself, all while trying not to get distracted by the cute girls around him.

Important to note:
Crimson High is a story-focused game, first and foremost.
For those of you interested, here's a list of some fetishes I'm confident I will add eventually (in no particular order; non-exhaustive):
- Objectification
- BDSM (not sure to which degree yet)
- Edging/Teasing
- Feet
- Spanking
- Role playing
- Impact Play
- Dom/Sub Relationships
- Voyeurism
- Anal
- Free Use (as in the free use kink (google it), NOT sharing LIs with others)
- probably a bunch more that I can't think of right now
Just for the sake of it, here's also a list of fetishes that won't ever be in the game (again, no particular order; non-exhaustive):
- NTR/Cuckolding
- Scat
- Urination
- Pregnancy/Lactation/Breeding
- Vore
- Sounding
- Age play
- Female domination
- CBT
- probably a bunch more that I can't think of right now
>>>>>>>>>>><<<<<<<<<<<
It's probably obvious for most, but just in case:
There will NEVER be an actual link to an updated version in the comments, no matter what the comment says - especially not from some random account that isn't me (VertigoAVN).
Any links in the comments are fake, and will most likely only infect your PC with nasty viruses and probably also make you be into that one kink which you really can't stand.

One of the devs I follow updates every month, one updates about 3 times a year, one updates...I guess around every two months unless something happens (illness for example), one is hoping to update soon(tm) but the last official update was 6 months ago...I don't mind waiting, especially if I know the update will be great!
"Perrine gives Vertigo some steak and a special salad made from local veggies" Gotta keep your strength up!
Thanks, mate. Appreciate it!
Low key would be really funny if you delayed the next release an extra month just to mess with damalon.
Dude, what the hell is your problem?
First of all, I don't owe you an explanation, nor am I under any obligation to check this site for comments religiously. The fact that I did do so for the longest time was a choice on my behalf, because I think that's the correct way to do this.
If you'd stopped for a second and used your brain, you'd have maybe come to the conclusion that there might be a good reason why I've suddenly stopped, too. A reason that doesn't have to do with you, because, surprise, the world doesn't revolve around you.
You want to know why the latest content release is taking longer than usual? That's because the frickin' update is longer than usual. Something that I've communicated very clearly, multiple times, both on Patreon and on here. If you're incapable of reading, you may want to reconsider your choice of entertainment. Just saying.
The next update will come out when it's done. If you can't deal with that, feel free to fuck off.
The nerve of you, I swear. I've been nothing but consistent for YEARS at this point. Regular, high-quality updates; immediate bug-fixes if necessary; open communication. And THE SECOND I fail to keep that up (for personal reasons, because I've been sick for a while and had to take a few weeks off, which, surprise, happens at times, because I'm human, too) you go fucking mental, just because I don't reply to you? Because YOU refuse to use Patreon and Discord? The two platforms I've mentioned I use a lot more than itch.io?
You're ridiculous. People like you are the reason why so many developers burn out. The demands you're making are just ludicrous.
Seconded. Take all the time you need, big guy. Can't rush quality.
Thanks, mate. It'll be worth the wait, and it won't be much longer.
If it helps, I think the vast majority of people agree this guy is pathetic. The message he sent that really got me irked was when he put "least they could do".
As if producing free content, and not communicating, is somehow WORSE than having just never produced any content in the first place. (Not that this is even the case here, but that just makes their stance even more ridiculous)
If only we could all be paragons of virtue like this guy and spend our time trying to make the world a worse place by targeting those who actually produce something for others, and doing our damnedest to make them want to stop.
You keep being you and sharing content with the world! The rest of us appreciate it! And if you ever feel like slowing down or just stopping all together - you have already done more than most people will ever do and quitting wouldn't change that at all. Although it would be a real shame.
Thanks, mate, that means a lot.
Some people are just too stuck up their own asses to see what's happening around them, or that not everyone exists solely for their entertainment.
No worries, though - CH will be finished, no matter what. Unless I go tits up, of course, but I don't plan on doing that anytime soon. There may be phases where I need to slow down to recharge, because being creative on demand can be draining, but those should be far and few between - and honestly, they are necessary, so there's no way around them anyway. Just like everyone else's paid time off and sick leaves and whatnot.
Appreciate your comment. :)
all that verti said,but also,yous a bitch lmao,enjoying free content and then being all pissy when it aint there at the time you want,pathetic bro,how bout you go make a quality avn on the level of CH and then you can demand shit,but nu uh,your dumbass cant even string two thoughts together,bloody loser bro.
Hehe <3
At this point, I'm tempted to. May just send it out personally to anyone but him. But I guess he's tired of this shit anyway, so I guess it doesn't matter.
For those who don't use patreon or discord;
Posted at 9:42am today Feb 3rd: Update at 65%
My guess life issues or something along that line I mean you can't always expect someone who to be consistent to always be that way sometimes they gotta take a break or they'll get burned out and no one wants that to happen
"The least you could do"
Them producing free content for you is already going above and beyond "the least they could do"
Like are you fucking kidding me?
I'd also appreciate them posting the info here, but wording it as "the least they could do" is actually crazy. You ask in another comment why the dev is communicating less? Probably because they got burnt out dealing with people like this.
update v0.45 (or whatever it'll be called since I believe this would technically be the second half of .44 that was dropped early. or maybe I am misremembering.) can't get here fast enough. I need more Crimson High in my life asap
More Touka !
hey so I made an account because I’ve already played on pc and it worked great, but I’m playing on an android now and it’s constantly crashing. I thought you know, it might be my device so I tried cozy cafe too and it worked perfectly, didn’t crash once. I don’t know if there’s a solution or what, I’ve already tried clearing cache, even reinstalling from scratch but it keeps happening. I was really looking forward to playing the last update so I hope someone has a solution.
In discord back on the 11th he posted the next update part was at 15% so my guess it's probably around the 30% mark by now
this is like the third time for me replaying the game. (lovely game btw) and i came across this picture and just have to know. is this a persona 5 reference?
Thanks, glad you enjoy it!
It's not an intentional reference, no. I haven't played any of the Persona games before, so any references in that direction are purely coincidental lol
it just looks so similiar, since it has the stairs in the background and even the bucket under the tv with a brown couch next to it, let alone the same flag above the tv.

but since you haven't played the games, how did you make that shot then? was it like a premade art already and you just added your character to it? (sorry for being so curious ;3)
These bots are just getting more and more brazen i came here to check out the page and instead of 2 different bots that are almost always there using different names there are now 3 of them jeez
It's crazy, isn't it? Crazy annoying, too. I delete a few of them every day, but there's always more.
Yeah its so annoying every single one of the games i follow on here has bots in the comments im always reporting them
Very good. Not sure if reporting actually does anything, but it can't hurt. Keep it up :)
So, I downloaded Crimson High via the official itch.io desktop app (I'm on PC, and Microsoft Edge said no). But when I went to run the game, it open the file folders (instead of just running the application like for other AVN's), and I don't see the actual application in any of the folders. Help please?
Hmm, I've never really interacted with the desktop app myself, so I can't say for certain. I just downloaded it to see if I can figure something out, but I get stuck in a perpetual captcha loop, so I got no way of actually checking what happens when you download CH via the app.
What I'd suggest you do is, first of all, get a better browser than Microsoft Edge. That one's just terrible. :P
Beyond that, though, the itch.io app should store the game files somewhere on your PC. If you can figure out where that is, you should get the same access to the game as you would if you were to download it from the game's page itself.
Alternatively, check out my Patreon. Not trying to sell you anything. The game is available on there for free as well, but instead of downloading it from itch.io (which may be what gives you trouble with Microsoft Edge) you can download it via Google Drive or one of the other file hosts I use.
If neither of those options work for you, let me know and we'll figure something out. :)
I ended up downloading it through the website on Firefox. When I installed through the app and clicked 'Launch', it opened the file folder instead of running the game like it should. And the application wasn't in the files. But I got it to work after using firefox, and I've been playing it the last three or four days almost nonstop! Can't wait for the next chapter (Since I'm on chapter 4 and have almost all the unlockables, I'm guessing chapter 5 hasn't been released yet.)!
I'm glad to hear that it worked out in the end, and that you've been enjoying CH over the last few days :P
You're correct in assuming that Chapter 5 isn't out yet, but we're nearing the end of Chapter 4 :)
Hey vertigo how are you lol just telling you you're game is cool and stuff here's to 2026 hehe ❤️
Heh, hey there. Doing well; hope the same goes for you.
Thanks, and to 2026 lol
Do you plan to add Spanish?
Not anytime soon. Once the story is complete, I may commission localizations in various languages. Until then, there are a few unofficial fan translations online that you could check out. I know there is one for Spanish and Russian, and probably some others, too.
I have to say this is the best h-game on this site I've played. I never expected to get this involved with the story or characters, especially Suzu, Jun, and Mana; with Reina, Yukari, and Aki being close behind. I'm anxiously awaiting anything you're doing next with this project.
same im almost as invested as if this is an actual show or movie
Love to hear it! Thanks for playing CH, mate :)
Outta curiosity Vertigo if I was to get a new phone would importing the files bring over my save or would I have to completely start over??
It depends on the phone, as far as I'm aware. Generally speaking, you can transfer your save files from one phone to another. The only question is whether your phone lets you access the necessary files.
As an example, on my phone (Redmi Note 13 5G; a bit older) I can access the save files by opening the built-in file manager, then navigate to the folder "Android > data > vertigo.crimson.high > files > saves", which holds my save files. However, I've heard from others that they can't or can't easily access the same files. If you're lucky, it's similarly straightforward for you, but there's a chance that you have to install a 3rd party file browser from the Play Store. And even then, there's a chance that your phone still won't let you access the necessary files. It's an annoying part of Android devices which I (currently) don't have a solution for. I'll try to implement something to work around this with the next update, though, since I need to figure out a solution for the Android version anyway.
TL;DR: If your phone allows you to transfer the necessary files, then yes, you can bring over your save to your new phone.
Another update finished and i already want more again. I don't think i will ever get enough of Crimson High. As always, great job and take care, Vertigo!
More coming soon! Ish!
Thanks, mate. Glad you enjoyed the update and hope you had an enjoyable time over the holidays :)
I can't load my previous saves with the new update.
There should be a way to jump to the latest update in game, instead of having to start all over again.
Are you playing on a pc or laptop? I'm on android and it works flawless...
Why would I add an option to jump to the latest update? Not only would that remove all your previous choices, but it'd also be pointless effort, since CH's saves generally don't break - I do my best to ensure that.
If anything like that happened to you, it's on your end, not on CH's. Instead of making obnoxious demands for a game you play for free, you may want to look into actually getting your shit together and not breaking stuff, then blaming other people for your mistakes. Especially if you're playing for free. Frickin' entitled people, I swear.
Wow, this is the first time, I "see" you being upset!
Nice update btw. Can't wait for Part2!
Merry Christmas, Vertigo🎅
Usually I'm not bothered by these things. I just really can't stand this kind of behavior.
Thanks, mate. Glad you enjoyed it. :)
Merry Christmas and happy holidays to you, too!
Why so rude? All he did was ask for a feature that many games gave
He did not ask for anything.
"Hey, I can't load my saves with the newest update. Is that something on my end, or is this a known issue? Can you add a feature to jump to the newest content in a future version?"
That's what asking for something looks like.
What he did instead was to complain, or to demand, depending on your interpretation of his words. Neither is really that great of an approach if you want someone to do something for you - especially if you expect them to do it for free.
If you don't pay for it or suck his D on discord you aren't allowed to comment or have an opinion about the game what so ever. Numerous very good ideas have been given previously on a certain pirate site and Vertigo always loses his shit, always goes on about 'entitled people' and 'free', imagine being such a pathetic dev you disregard good ideas and actually improving your game because those people don't pay.
Is the game even worth playing?
It pains me to say to this because the dev is so toxic and egotistical but I would say it is, is it great, no not really, but it's a decent read, I would say the worst part of it is the MC is meant to be a detective but at times he's super dumb, it's frustrating to read them parts.
got my computer working again just intime i wouldve been sad if i was late to the update
I'll be honest with my first try of the game being a bit hard to get into but after giving it a second try i really loved it.I really got hooked during the middle of ch one. The game is pretty well written with each character feeling unique and enjoyable. All i gotta say is Nagisa is best girl.
Glad you enjoy the game! Maybe eventually I'll find the time to rework the early game, to make it less rough to get into. :)
So I had to replace my phone recently, and lost all my progress on CH. I reinstalled it and used an auto clicker to skip past everything so I would be ready for the new update. It speaks to the quality of this writing that, even when I was trying to skip through it, I got sucked into the story and went through it like normal.
This second go around also lent me some insight, like what kind of Myths Meri and Mei might be. It's just so good. I look forward to the next update.
Heh, that's actually awesome. Thanks for sharing!
And I'm glad you found some more potential hints. :)
i just go into the settings and turn the auto setting to all the way down its goes so quick too no auto clicker needed
I normally dont comment but ive been noticing lots of bots that are likely attempting to spread malware recently pretending to be giving out updates and acting is if its legit and safe to download for a plethora of different games not just this one so my question is this is it a new occurrence or has it been happening for a while already
Hey. Yeah, it's been a problem for a while. It started over a year ago, went on for a while, then stopped (at least on my page) for a few months, until it started again a few weeks ago. And now it's worse than ever, with bots called "Developer" and seemingly legit messages. I've been deleting 1-4 of those per day for a bit now.
Well, it's looking great. Still incomplete, though.
Currently debating whether I want to release the update in two chunks to reduce the waiting time, because there's still a decent amount of work left before full completion.
Sure it does, otherwise I wouldn't have mentioned it.
I'd initially planned to make a post on here to ask about it, too, but after doing so on Patreon, I got a good idea of the average opinion (namely, everyone wants different things) so I decided to sleep on it and make a final decision tomorrow. It's likely going to be a split, though, since there are no downsides for anyone, unlike with waiting for the full update.
any reason why pregnancy wont be added, just curious
Mainly because it's a huge turn-off for me, personally. I don't mind adding things I'm neutral towards, but anything I actually dislike I won't add. If you enjoy pregnancy content, that's fine, but it's just not for me.
No pregnancy is a bit sad but understandable the story makes up for it
same reason for no fembom and boob milk? i feel like it would work very well in the plot tbh
Yes, exactly the same reason for those two. While it might work with the story, I'm just not into it, and thus it would probably turn out subpar - I'm lacking the subjective understanding of what actually makes these things desirable, and I don't think reading up on something like that can substitute actual, felt desire/attraction.
Me personally I think people like pregnant bc its the way for creating new life with the one you love pregnancy doesnt have to be a sexual kink
You're right, of course. I assume that's a big part of it for a lot of people - or even the whole reason.
It doesn't change anything, though, because it clashes with my personal views regarding pregnancy
What I will say is that there is a chance for pregnancy in the story's epilogue. At least one of the girls (no details; don't wanna spoiler) lends herself well to the role of a mother, so I may make an exception for her/them. But as I said, it's not guaranteed.
When I finished the game at end I just stare at my mobile screen thinking why it's end at an unexpected moment btw waiting for new update
What can I say its a long game I am playing it in my Android for like 4/5 days and still even finished it btw playing it 4 hours a day
This for those that ain't on discord, if you're wondering about the next update as of yesterday Wednesday October 29th at 3:24pm the 0.44 update is at 85% complete
this is a very good story not so much a game as just a story there are no points to make any storyline choices but i like the story i'm going to make an assumption that in the next update suzu, miko and kuro and the MC are in fact going to have a foursum on their fieldtrip in the next update
Vertigo askleepy made the series I hope you have your fun time watching he go insane t trying to figure out the villain 😂 also what was the collaboration you did with a game awhile back I honestly forgot
there is a brief mention of the game in world crossing academy and the auther of wca said that they had some help from vertigo on something i cant remember what but i do remember asking
That's awesome! I'll put the first episode on my watch later list and check it out when I have some free time.
There are crossovers with both World's Crossing Academy and Fall of the Angels in Crimson High. :)
He's figured out a schedule so there's more videos (he's on episode 11 now lol)
Okay listen here you, how DARE you make a story and characters that get me so invested and attached to that when I reached the end of .43 and it said that there was no more I actively stood from my chair, palms flat on my desk, and screamed "NO!" as if someone had just committed a horrible crime!
Being serious, holy CRAP am I enjoying this experience, iit's right next to Harem Hotel on my Top Five VNs now. You, good sir and/or madam, have earned yourself a fan. Keep up the good work, I look forward to seeing how things progress!
Hah! Sorry about that. I did not mean to make you get out of your chair. :P
That's actually really nice to read. Thanks for playing CH and enjoying it! Top 5 is a really nice turnout :D
You're a wonderful storyteller, and I look forward to .44 and beyond with great anticipation. Keep up the wonderful work, I'll be sure to keep this firmly saved away in my 'Must Track' savelist. o7 Have a good day/night!
Thanks a ton!
You have a lovely day/night as well!
Anybody here can help me? I just got back after I stopped playing the game on ver 0.38. And after I DL the latest version 0.43 "update only" there's an error where I can't see any image only text. What to do with this?
The update-only version is only to update from one update to another. So, in the case of v0.43, it's only usable if you have v0.42.
To update from v0.38, you'll have to download the full version.
Ok thanks
hey man i've tried to DL the full version but it says "couldn't download no permissions"
That shouldn't be the case. As far as I can tell, the download works fine
We're getting there. Update's not too far from completion, and it's a good one.
I'll make another dev log on here sometime this week, where I'll go into a bit more detail
Umbasa Everyone! hope everyone is alright and healthy. .
When Nene bares her fang, it is just so adorable!! I know she's self-conscious about it, but she really shouldn't, she's so adorable! (Still can't take Perrine away from most adorable though)
When we go on the field trip Kuro promises right before the end of current content, is Kuro planning to "ambush" Ren, like Machi and her sisters did? Is Kuro going to see if she can scare Ren with talk of hooking up with Morrigan? Is there going to be someone new trying to scare people, only they can't because they are too short and it's weird being scared by someone a foot shorter than you? (I realize all of this is extremely unlikely, but hey)
Anyway, this showed up on my feed a week ago or so, so it's waaaaaaay easier to find now! Just need to wait for few stuff, and wonder if Miko and Suzu plan to ambush Ren with his favorite food for a surprise dinner!
What is sound and CBT? I'm not sure what those fetishes are so don't blame me for asking.
CBT - Cock and Ball Torture
Sounding - sticking things in your dick
So yeah, Vertigo blacklisting those sounds good to me.
okay simply from the dad jokes when the MC calls his father, I've decided I'll rate the game. Not right this second but I will. Dad jokes, puns, play on words with the name Yuu, absolute gold, story and content is great too.
Heh, nice to see someone who can appreciate good humor :P
Hey vertigo could a friend of mine named askleepy do a YouTube series on your game? (They are probably already getting the series ready)
Hey there. Sorry for the late reply. Yeah, your friend can absolutely do that. :)
Could you say a few nice words about him just wondering lol 😆
Hey Vertigo any Idea, when you'll finish this update? This waiting period is so cruel...
Back on Tuesday the seventh at noon on discord he posted the next update progress at 70% so I'm betting by the end of the month to early November for the release
Thanks for your reply! So there is a light at the end of the tunnel🥳
Heya!
I don't have an exact date yet, but we're getting close.
I'll make another dev log on here sometime this week, with a bit more info on it :)
I cannot wait for the update. I am so looking forward to it. I've been replaying the full game to refresh myself and notice some things I didn't before. not much but some things.
Soon!
