Amazing base mechanics. I think that you should add a brief window before you get another bullet. Because you can shoot to many bullets at once and fly forever. Also making sure that your effects disappear. Also making it so you can die. But I see lots of potential. I would suggest that you add a melee attack that when you hit stuff gives you bullets back immediately compared to hitting perfects giving it back to you slightly slowly. Or you could just add death ceilings. But overall a great game and so fun.
