Really liked it overall! The ambiance feels great and it was a lot of fun to play.
Like was already mentioned, the hit feedback does feel like the next thing you should add if you continue to work on this (which I would love to see). This might also help with figuring out which beat/melody note an orb corresponds to, which I occasionally found a bit confusing (could also just be a skill issue). Although it might just be that the game desynched for me, as I always got a few more notes after the music had already stopped completely (unless that was intentional?).
