Man. The music is top-tier. The breakbeats really took me by surprise! And playing it is truly like a gift for my eyes, the visuals are very nice!
The gameplay is a little funky, I can't really see where my waves are going, and I don't really feel like I need to use the square wave, at least at first, since I seem to have infinite jumps. But the fact that I can see what wave I'm shooting is very helpful. If you had a tutorial level and polished out the shooting, this would have been perfect.
