Seriously though, awesome game. When I was brainstorming for the 4 colors jam, the Game Boy style of palette came to mind, and I'm glad it got to be fully explored in one of the games! (Also, thanks for fixing up the hit boxes.) AND this is was your first game, that's super impressive and a massive first step into the development process. Great Job!
