Really cute! I like the art style a lot. Took me awhile to figure out how to rotate blocks on level 3 since it isn't mentioned in the game and I didn't check the jam page immediately, so instructions are probably worth adding for that. I also found that the levels still showed as locked after I beat them, though it would let me click on them. Those are minor gripes through and overall this game was pretty great!
Also congrats on making your own music, also nice to see that in a game jam! It's a real bop too, props to the composer!
