Hey there! Please consider giving ANONIMATO a chance! It's a six paged player's handbook (with a DM book that is still getting a translation) inspired by works like Kaiji and Zero Escape games. The books rules are flexible enough to accommodate your preferences. If you like TTRPGS with more focus on roleplay or puzzle-heavy you'll probably like it.

ANONIMATO by Jemie Les (itch.io) I'll give more communities copies for each copy sold, but contact me if you still can't afford it and still wants to play.
