My favourite game I've played of the jam so far. So many little details that work like the earworms, looking like the fingers you play the game with, the environments changing in the background, the visual effects on a streak, and the music was wonderful, which is definitely key for a rhythm game to be enjoyable.
Small nitpicks: the sound effects for hitting notes are maybe a bit too loud by default and kinda overpower the music, especially when you're holding, which is a shame when the music is this good.
