I loved the song. But the controls were hell on my hands. Or should I say hand, as you use ASD and Space. But the music was really good, and I liked the progression of the levels to the end.
There's a little controller icon bouncing around in the Title Screen, if you press "S" while touching that it'll take you to a Controls Screen where you can remap the keys (need to use the mouse to select the keys at the moment, but that will change).
