This is a really neat concept! I love the level design, and I thought the persistent banners to the left and right to show the interactions were effective. I have been having some issues getting it to consistently register my movements, and it would be nice to have a sort of "sandbox" mode to figure out what works well. Unfortunately I didn't get enough right on the first track to proceed, and I was surprised to see the game asked me to exit and restart (or wait like 3,000,000 hours). It would be nice to have a "try again" button or some other way to do it without exiting the game. I didn't find an exit button so I eventually had to ctrl+alt+delete out of it. Overall when it did track successfully it was really entertaining, and I think if I practiced for longer I would get the hang of it better. Thanks for sharing this!
