Hark! th're beest demons haunting mine own harpsic'rd! I loved the unexpected part - it went from a simple beat game to a really challenging, unique experience. (Plus I got to listen to Canon in D which is always a bonus). One critique I have is that the level of difficulty went way up and resetting always put me back at level 1. I would have appreciated a more gentle learning curve or at least a reset to the third level. I think you did a really great job with this, and the unexpected twist added a whole, awesome new complexity to the game. Great Job!
