This was pretty fun! I like DDR / FNF type of games, so this was up my alley. The notes shifting around is a fun challenge; the only thing that took me a while to get was that I was playing the person in pink vs the person in green. The artwork is grungy in the best way possible, and it's fun spamming the notes to make the sprite dance when it wasn't my turn. Overall great job!
Edit: For more context to my feedback, I was playing in expert mode.
