The music you chose fits the game perfectly, it really pulled me in and made me feel immersed while playing. The mechanics are excellent and a lot of fun! I did run into a bug with the button boss, though. After I died and reset, I bumped into the first button to start the fight, but it got destroyed without triggering the battle. The game does take some time to get the hang of, but once you do, it's great. Awesome game!
