I suck at bullet hell game, so I appreciated the fact that you just counted the deaths rather than straight out punish the player and have them retry!
Liked the art style, maybe not so much the backgrounds but the animated heads were very sleek and well animated!
The mechanics of the ball could use some fine tuning, I wasn't sure how well to use it, so I just ended up rotating it around me with A W S D A W D S A, etc. The idea of un-linking the ball is very cool and like it at lot. I couldn't make a great use of it though because I was so busy trying to dodge the bullets! (again, I suck at bullet hells)
