Not bad, just...
...Needs some improvement. It was an extremely good idea, the music was simply awesome, and the moves were pretty cool and funny. I actually had trouble on the first one on easy, maybe it's just me. I really liked how you didn't stay with the pack on the "Rhythm" game with the arrow keys, and that was what really made me happy to see a game like this. I really enjoyed playing your game and hope to see more excellent work!
