I tried running it on Linux, I instantly see the "The End, thanks for playing" screen after pressing Play.
I'll be able to test it on Windows later today or tomorrow, I won't rate it for now but just to give you a heads up
Also congrats on using Pygame! That was my first gamedev lib, and I know how much work you have to do to get anything working (but also the satisfaction that comes with it when it finally does work)!
