I loved this! It's a fun little take on breakout with some interesting new mechanics.
I had a few thoughts while playing:
1. The chiptune music works really well, but the volume was turned down by default. I think I would have liked it louder.
2. On some levels, you can launch the ball straight up and it leads to a situation that's akin to cheating. Because the ball never goes at an angle, it clears everything directly on top of the player. If you could randomize the initial ball angle, it would make the game more challenging in an interesting way.
