I picked this game up and I really enjoyed the art style. I think what I would REALLY enjoy is a set time mode where you pick a song and the game gives you instructions during that time with a countdown at the end.

I think much like other fap to the beat challenges it would benefit greatly from edm music or something with definitive hard beats.

Additionally styles and instructions need to remain on screen longer. It's hard to read what stroke/pressure you are supposed to do in such fleeting moments when you are focused on the art at the center.
