The hands are currently running on static animations that just loop over and over again. Since the notes are randomized and are spawned pretty fast it would probably make the hands really janky if I pulled them towards where the notes appear. I was however originally planning on integrating a midi system where the notes being player are the actual notes being played in the song. It made it a bit too easy, but I might be able to do something with it in the future that could possibly support your idea of moving the hands appropriately.
In any case, thanks for playing and I'm glad you liked it! :)
