I finally finished this game. It's called Press a key you would like to use, and you can download it HERE. PAKYWLTU is somewhat inspired by a game called add special instructions, which adds a new keyboard key each level. My game is similar to that, only every key in my game is user-defined.
I'm very satisfied with how it turned out. I might return to it later, and add some sort of audio/music, and maybe a just few more controls. But that probably won't be any time soon.
