Really nice game, i liked the brightness mechanics, and I loved the upward motion through the one way platforms that felt so smooth

wow tbh i initially had low expectations because of the graphics xD but the game turned out to be pretty fun!! something about it makes you really wanna know what comes next just like the other guy said

i like the mechanic!

I found myself enjoying this more than I initially thought I would. Shifting the color tones around to dynamically change the environment was really clever. The signpost that explains it was very welcome because I was confused until I read it. It's a hard game to put down because it makes you want to push on and see what's coming next, which is good design.
If I was going to nit-pick I would say using a, d for left, right and space for jump feels a little awkward, but I understand why seems you use the mouse as well. Other than that, I had fun. Great entry!
