It's kind of fun once you get past the initial movement change. Few questions and a few constructive points. What is everything? What is the thing in the middle and why are there eyeballs flying at it? Do the eyeballs move to the rhythm at all? It might be a but out of sync if it is. The collisions are a bit off also, a few times the eyeballs slipped past my shields but didn't end the game, just treated like a shield hit. Game states would help a bit. The first time I loaded it, I guess it started when I wasn't looking and I died. So when I looked up and saw the 'sphere' in the middle and it was moving when I pushed the buttons I couldn't figure out what I was supposed to do because there were no enemies. Maybe make the 'R to Restart' a bit bigger or more stop movement/remove the sphere on gameover. I played it a few times though, got 1300 on my last try. A good start.
