Congrats on finishing your first game jam game! I do have some critiques, but I hope you take them as constructive rather than an attack on your game. As a platformer I will say it was ok, but it fell into a lot of the traps that plague most beginner platformers that utilize physics, particularly no rotation lock on the player or movable objects, which caused awkward rolling off of platforms and getting orange blocks onto buttons really inconsistent and frustrating, inertia causing movement both for you and orange blocks to be really floaty, as well as friction causing you to get stuck on walls when moving forward while in the air. I also felt that while the idea of seeing the "real world" causing madness was a decent idea in theory, in practice it often forced a lot of standing still waiting for your sanity to regenerate, which was rather tedious, especially since the ring that showed the real platforms was so small that you usually couldn't really get a good understanding of the environment with a rapid activation. Usually in a lot of games (aside from maybe stealth games) mechanics that enforce frequent waiting periods are often discouraged. The last thing I wanted to critique was the font used. It does have a cool sci-fy, alien look to it, but functionally its just a little hard to read. It's nothing big, but it does slow down reading a bit enough for me to make note of it. I did like the bgm, and I think you could work on the things I mentioned to make much more polished things in the future. Best of luck on future endeavors!
