I agree with Manitoda that the ball can get a bit lost in the breaking effects.
Not having my thumb position be 1:1 with the paddle placement can feel a bit weird.
Balls colliding with each other was unexpected. Not a huge fan.
Other than that it's fun. I like the art style and the upgrades. Themes are a fun touch and I'm interested to see what you do with that. Uke / Tori theme when? I haven't touched Arcade or Zen yet but will report back when I do.
Also sir voice reveal on the countdown?
