Probably one of the hardest games of the jam I've played. Enabling triggerless mode definitely helped to enjoy it more. Fun to try out with your own songs although it didn't seem overly affected by the song.
I played like 15 rounds of this before figuring out how to use the power-ups. Also got to a level where it asked me to knock out 1 more but there's 0 marbles left on the board.
Good mechanics and really nicely polished, feels like a real game. Only lacking some progression when you play further. I got to level 15 and it didn't seem to be getting any harder so called it quits there.
