Rainbow Rhythm is a small rhythm arena for you and your friends. Notes fall, you hit them on time, and your citizen dances better the better you play.

Every round the lobby votes: first the song, then how many keys — 3 if you want it chill, 4 if you don't. Everyone plays the same notes at the same moment, so the scoreboard actually means something. When the track ends, you vote again. That's the whole loop, and it's a good loop.

Miss a note and your combo dies. Mash keys and it dies too. Play clean.
