I like the idea! When I realized it was like the "ball" of an air hockey game, the way the game feels "clicked". The art was visually clear, and I quite liked some of the visual effects; in particular the "burning" effect once you're out of control. I didn't like the music as much?
The game felt a bit too fast to be able to tell what's going on, and there was not enough time to react to enemies suddenly appearing from the edge of the screen, though I guess this is part of what makes this game feel out of control. I liked the fact that you didn't lose as soon as you had no more HP, that's an interesting design choice.
Good job!
