Great game, but there are some little things that makes the game bit unpleasant. I'm playing on Switch and it's not really clear and easy to navigate through the menu.
The game become really hard when balls can switch side at the last moment, I feel like it's super random and it don't feel right for a Rythm game.
Another thing that to my mind would make a great rythm game, is about sound design. What if each of the 3 moves have differents sounds effect, so you can play the game blind. (Pretty much like Rythm Paradise when with one sound you can predict the incoming move)
