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.

The updated version of this game HERE
[NEW VERSION!] Updated Version - https://rottmutt.itch.io/ <=== new update release
The updated version of this game HERE
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
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
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.
Hina! What an Angel!
Hey, so hows CH looking? Hows it cooking?
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.
well my vote is to split it up, if that counts for anything.
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
Yo! So how's progress on 0.44 going mate?
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
Ok, thanks.
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!
Still can't find you through search, which is weird because another adult dev has a few games that include Crimson on the search. Are they punishing you because it's such a wonderful game? Is it because Ino and Aya are such adorable weirdos? Is it because you keep putting the end of an update on a cliffhanger?
Anyway, hoping things overall are good with ya!
So I'm NOT the only one, not being able to find CH on itch.io🤔! Reassuring...
I made a progress report on here a few minutes ago. In it, I do cover this topic as well. :)
And yes, things are going well, thanks!
Yo Vertigo, I hope you aren't going to change to a longer dev time permanently.
One of the things that stands out about CH the most for me is that superfast dev time. It really puts you above and beyond most devs, in fact I often compare other devs to you and find them lacking.
I dont mind a one-off instance, but please dont make it permanent! I dont want to have to wait too long before I get my next fix!
If you're doing a vote on Patreon or something, please dont ignore your Itch customers! I pay good money to fund you too, so I'd appreciate having a say if it comes down to voting.
Hey.
No, I'm not going to keep the longer dev time. I made a progress report on here about it just now, explaining it a bit more, but basically, this is very much a one-time thing.
There won't ever be a vote regarding things like this, either. It's something that I need to decide for myself, because ultimately, it's about what works the best for me, and what I can sustain the best in the long run. If I'd come to the conclusion that longer update cycles worked better, I would've gone with that - cause there's no point in going with something that'll just make me burn out in half a year. Luckily, this update's already shown that my previous approach was the better one - but that was kind of clear from the get-go. This was always going to be a one-time thing.
I very much enjoy being able to release new content on a frequent basis myself, because that way, I can get feedback and reactions more frequently, too. So, don't worry, things will go back to normal(-ish; there may be minor changes to things) after this update is out!
When is the new update?
Vertigo posted recently that the next update he is working on is going to take a little longer than usual but its also going to be more content than usual too.
He did not say exactly how long it would be.
Normally we would still have about a week to go before one of his usual releases would hit the interwebz. But as I just wrote, this one is bigger than usual so who knows?
Hey everyone
Is it just me, or has CH really not returned to itch.io ? While most other VN's are back, I still can't find it there...
Not sure what you mean mate. CH hasn't gone anywhere.
I believe I read in one of the updates that Vert is working on the next content release and its going to take longer than usual but also be bigger than usual.
I made a progress report on here a few minutes ago. In it, I do cover this topic as well. :)
I was brought here by Worlds Crossing mentioning this VN, and am glad I gave it a try. Truly amazing story, can't wait for more. Keep up the amazing work.
lol had this game on my trying soon list for a while, and now that saw it being mentioned in world crossing academy, a small episode of mc with a little girl called Rin i should probably play this one next
speaking of small... the mc looks big in the screenshots making everyone look smaller than they probably are haha
WCA was what finally brought me here too. Love the nit of how both games note each other through (legally not) Netflix shows.
Hello Vertigo, I'm Brazilian and I would like a new translation in the last update, do you have an estimate of when it will be released? (Crimson High is my favorite game 😭, I need an update to play)
Hey there, mate. I love to hear that CH is your favorite game!
However, if you've played a Brazilian Portuguese version of the game before, it wasn't made by me but fan-made instead. As a solo developer, I don't have the time (nor the language skills) to translate CH into other languages. Once the game is fully done, I may hire people to translate the game into various languages, but until then, all there will be from official side is the English version. With that in mind, I sadly can't tell you when the last update will get translated, cause I don't know who's responsible for that. Sorry about that!
Oh, okay, it's a pleasure to talk to you, maybe within the next month some fan will do a translation, that's what I hope, right? Sorry for sending several similar messages asking about the translation, I really wanted to ask this, because this game ended up becoming my favorite, thanks for understanding.
No worries, mate. I get where you were coming from, and I would never fault anyone for liking CH too much :P
Fingers crossed that there will be a translation for you soon!
just got around to downloading the update and tried to play only to end up at the same screen where the last update left off wow great update, apparently i downloaded THAT version and didnt download the new shit so yayyyyyy time to download it again and get the right version this time:|
Ah, shucks. You hate to hear it :D
Hello, Vertigo, can you make a Russian translation of your game? It's hard for me to understand the game. I hope you'll notice my comment.
But that's only in my dreams.
Hey there!
As a solo developer, I don't have the time (nor the language skills) to translate CH into other languages. Once the game is fully done, I may hire people to translate the game into various languages, but until then, all there will be from official side is the English version. However, there are various fan-made translations for the game around. Though, important to keep in mind is that I cannot give a guarantee for either the quality or the integrity of those versions. Downloading them is at your own risk. Sorry!
Crimson High - it's like that style of doujinshi "wanted a pron, stayed for the plot". It's the most interesting game in genre I played so far. Even "harem" is explained, I didn't expected many things going on here. I wish to see more content with Kana, Miko, Suzu and Okami.
Good luck with your game! Can't wait for new updates
Thank you. Glad to hear you enjoyed the game and its story!
She wants to be "by herself" or "myself" as she says, "By Myself" being a song from the Linkin park Hybrid Theory album. So thats why I made this.
Very nice!
