This is quite polished and well-executed! You did a lot to give each song unique visuals and animations, and I dig the art style. The gameplay felt tight, and adding calibration for the offset was a nice touch. I would have liked to see a breakdown of my score between songs and maybe again at the end, but I totally get that in the time crunch of a jam you can't necessarily fit in everything you want, and there's a lot there already!
Also, you made these tracks yourself? Absolute bangers, every one, and I see what you did incorporating the theme into the song lyrics. 🎵
