The ball doesn't follow the perspective projection! O_o
this makes it silly to play, you have to keep tilting it left or right even when you're going in what the view would have you believe is a straight line.
I'd love it if it was longer.
The bosses are a bit too easy, I could just stand in one place and smack them to death with no risk to myself, just keep hitting them against a wall.
The blue and yellow shots are way too hard to see, I got hit a couple times without even knowing I was being shot at.
4/5, keep up the good work!
