Really cool idea, original, fun, kind of chaotic! Art is on point, game design is really smart, I had so much fun playing it. After some time it gets boring, maybe because it's the same thing but a different pattern. Consider it adding different kind of enemies and challenges. I believe getting an S rank(no ship damage etc etc) on every mission is already hard but maybe more features would be cool. I loved it, great submit, never seen anything like this before!
Have you checked my game yet?I think it would be fun, leave it a rating if you could!
