I got to level 9 before I had to give up. The levels go pretty quick, and it’s pretty easy to figure out without reading all of the rules. It’s Music Bounce, something loosely similar to Arkanoid, but patterned around music.
You open little gateways on the left that release a ball onto the playing field. If you open up the right gate, a ball will bounce along and clear away all of the tiles it happens to bump into, which form the beat of a rhythm. You’re only allowed a certain number of gates to open at a time, and you’ve got to clear away all of the musical tiles for at least one moment (because they regenerate). It’s easier than I’m making it out to be, so check it out. And see if you can get past level 9 ^_^
