The visuals here were so good, haven't played another game that looked quite like it. As others have said, it was quite hypnotizing and it also felt a bit 3D to me, like the colours were popping off the screen. Music was also great and had a lot of fun playing. Would help to have more feedback when shooting the bosses, I wasn't sure if I was damaging them at first. A health bar would also help. I also came to a point in the game where there was no more enemies, waited a couple of minutes and nothing happened?
Overall, fantastic job guys!
