Solid controls, good music and casually difficult, got the KBC and 1000+ points on my second attempt. The quality of the music was great. The visuals could have been more specifically in sync with the game, for example the floating eyes in the background don't seem to scroll in tempo with the music. It doesn't really affect gameplay necessarily, but I expect that sort of thing in a musical based game. The character options seemed unnecessary, unless I was missing something. It would have been cool if the song, and therefore the level, changed depending on the character. It's not the best musical scroller I've played, but definitely enjoyable and easy to pick up and replay.
