I really enjoyed this submission! I loved the visuals of the blocks, and thought that the keyboard controls were inuitive (although I did use the mouse for a some navigation). Like others, I had trouble, mostly with the accompaniment, but I really enjoyed making progress on the main track.
If the Check Screen showed how many off I was, then I think that would have helped me know if I was making progress, and be a little more eager to complete the entire track.
