Very interesting game play, I enjoyed it a lot. The waves sync very well with the beats and the visual feedback is excellent. You even have multiple levels with properly scaled difficulty, good job! It would be really nice if you can have a sensitivity slider for the wheel control so player can adjust accordingly to his/her reflexes. My only big concern is that after getting to a new level you don't allow time to read the lock combination and jump right into unlocking it. How am I suppose to unlock a chest without knowing the lock. This can be quickly fix by having immunity (aka not decreasing points) for the first 2 or 3 beats so there is time for preparation. Overall, quite an innovative game, well done!
