LOVED this game. Right off the bat the music was awesome - the mix of chiptune and piano was killer. I saw and played the re-balanced version of the game that you posted below and the feedback I had (that the paddle controls were a bit wild) was addressed in that version.
I found some maps extremely challenging due to the placement of the unbreakable bricks, but this didn't happen super often.
Kudos to a great game, and if you get a chance please check my game out too - it also incorporates Pong. https://itch.io/jam/game-off-2018/rate/338739
