This was really neat, I loved how the player literally rolled around and all the barriers are individual notes.
The puzzles were simple yet made me think a little bit, and I don't know if it was intentional but there was one point I was able to slide the blocks through a wall lol.
The various "moves" were neat, I especially liked the "Ur Ned" line! And they played well with the little Simon Says puzzles.
Oh, and the ending was very funny!
Excellent work!
