This is a pretty fun idea. Course, still some kinks to iron out, as has already been mentioned, but for 10 days this is pretty good. The sprites look good, I was hummin' along to the music, and I showed those cygoblins what for while spinning around in space. Turns out if you bonk your head just right, you'll be able to spin. This part might just be me, but there are mirrors in places where there doesn't really need to be? Maybe I had my angles wrong, or maybe they're there so you can have multiple ways of doing the levels, or any other amount of things that just flew right over my head, but I couldn't see a way to use them. If they can be hit, then that means that you made levels that can be done in multiple ways, which is always a nice bonus. Good work
