Completely incomplete game. Published only because why not.

Explained in game, but there's also F to fullscreen, and you can actually use most gamepads to some extent too, even if you won't know what buttons to use.
I don't know if I'll do anything, the code is super messy, but I like the concept and the narrative that I didn't get to develop. No spoilers.
