Overview:
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.​

Spoiler: Developer notes

If you need something from me, join the Discord. I won't react to (or even read) replies in this thread.

Version numbers for updates go as follows:[major version] (dot) [minor version] (dot) [hotfix]
So, in other words, new content is generally only available when the number in the middle changes (e.g. 0.25.0 → 0.26.0). If the last number changes, it's the same update but slightly polished in terms of typos/bugs (e.g. 0.25.0 → 0.25.1).

Crimson High is a story-focused game and sex is just one element of it. If you're looking for a quick fap, look elsewhere.
But if you are indeed looking for a story that builds up to intimacy between the characters, you are in the right place.

Feel free to head over to Patreon as well for exclusive content (renders, special polls, custom GIFs) and development updates.
I'd be happy if you wanted to support the development of Crimson High, as it helps me increase the game's quality, and ensures that I'll be able to do this for a long time. If you want to support, but can't do so financially, it would be great if you leave a review here on F95 (5 Stars of course, lol) or just tell your friends and family about Crimson High, so they can play it, too!

The game's atmosphere relies on its music, so it is advised to not mute the game to fully enjoy it.
Tips on where to find the Hamsters for the Extra Gallery can be found on the game's

this looks like a sandbox game... so is there sandbox???

No, it's strictly story driven with decisions, no sandbox.

 

[Slavious]

this is a fun slow burn story game. while it does natter on a bit much for my ADHD, I like this genre of story so I just skip the pointless or repetitive stuff and its ok.

Happy its not sandbox. so many of these types of games are and that always leads to disappointment haha. This dev/author has figured out how to have you "explore" a scene in an interesting way without having you running around mindlessly guessing which room is next over and over praying its the right time of day haha.

Also seems like there are a nice variety of types of girls which is always nice as well.

It's a cute, pretty wholesome adult game. I like it. It's another one where I wait a few updates before downloading, just so I can have some content to play through.

 

[Krylo]

This one is good yet frustrating. There is decent progress with the LI considering only like 2 weeks have passed in game time, but the problem is it's taken around 2 and a half years to make those 2 weeks. The ever expanding cast also doesn't help with making it feel like progress is slow. You can only interact with so many people in a day.

 

[nightshade]

I absolutely love this game and is my personal favorite. The story kept me engaged the entire time.

Yes because it is not a typical porn game like "meet and fuck" but rather a slow burn romance game so if someone doesn't like slow burn games, unfortunately this is not game for him.

I agree.

I guess I have to wait two more years for some more action with Jun.

 

[Joebobby]

Every time i see an update for this i instantly download, shame the content in each update is so small but I would still recommend it, maybe give it a few updates between plays though

I love this game too, though I agree with the small updates. The worst part is it ALWAYS ends in a cliffhanger... (the one update a balconyhanger)

 

[AggressiveCheeto]

i just don't finish the updates so i don't have to deal with the cliffhanger

 

[LongSlongSilver]

we really need character bios, a girl pops up and i have no idea who or where i have seen her before

 

[AzraelSteel]

Yes because it is not a typical porn game like "meet and fuck" but rather a slow burn romance game so if someone doesn't like slow burn games, unfortunately this is not game for him.

There's two aspects of slow burn, though - the story could be a slow romance, and that's fine, but if that slow romance is spread out over several real-life years, it starts to feel too slow.

 

[LevverSan]

My absolute favorite, I love the game, I love the story and that it doesn't progress too quickly, just great. I love all the characters. you have a wide range of different emotions and types of people (not human characters).

 

[Ren567]

what does the unlocker do?

 

[MaximMuster]

The unlocker unlocks the galary so you don´t have to play the game to see the spicy part.
