Crimson High [v0.42.1] [Vertigo]

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.

Developer Notes:

If you need something from me, shoot me a DM or 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 Discord.

Tags that won’t ever be in the game: NTR, Vore, Scat, Femdom, Pregnancy (including lactation)
