Absolutely no skill
How are you suposed to be good at this game? You just hold down space and move, pretty much, wherever. You try to avoid the enemy notes, but if you do manage to see the incomming fire, its usually too late. So for a game it wasn't that good.
However this submission had a lot of style and good graphics, except for the boring background. I think this would have been better as a movie with some tweaking. It was entertaining, but not as a game.
