Wow... Just wow. Absolutely brilliant. The gameplay was only passable, but the backstory, the computer character... I only kept playing each replayed wave again and again just so I could hear the end.
I think the notes should have a smaller window to hit them, too many times I try to hit a string of doubles but because I left one out previously it hits that one and it goes all un-co. Un-co-ordinated, if you didn't understand me.
