I liked this! I think you implemented the special object and theme quite well, and the game itself was short and satisfying. Easy to understand mechanics and puzzle.
The amp feature where you keep playing notes to increase the noise levels was quite clever and original. I guess my only concern is that I can still die if I get hit by a CD during the screen transition between rooms (when the screen is fading to black). It would be nice to be invincible when the screen starts fading to black between rooms, but that's a minor thing. There were no glaring bugs or issues that I noticed anyways.
Good job!
