This is really cool, but the controls are frustrating. It's really hard to get your notes in the right place when everything is happening, and it feels really punishing if you're pointing the wrong direction.
I will say it does getting some used to, and if rhythm(ish) style games aren't your type of game that's alright, not every game is for everyone!
A personal tip is to listen to the music as opposed to looking over at the right whenever you want to place notes. Feel the beat rather than just trying to time it by looks.
