Genius idea. I like it a lot. Just a small technical thing, the notes wouldn't go; G, G sharp, A sharp, A. Instead it would go; G, G sharp, A flat, A. Unless you already knew that and did it for some reason that I haven't figured out yet. Still a great little game.
I played day 5 on easy, and using nothing but nailers and no support powers I got to level 18 with no deaths, just line up nailers at the beginning and then just put tons behind them, it is the most ownage you have ever seen.
