Fun concept. At the beginning I was way to overwhelmed with the controls, but I got the hang of it. Though I'm not sure if there really is a high "skill ceiling" as I didn't manage to get much better than "intelligent spamming" xD.
It feels a bit weird that you loose with a lot of balls still on screen (which is atypical both for pinball and breakout). I would suggest maybe changing how lives work so balls gradually get less and you loose when you loose your last ball.
Other than that great game. Thank you for creating it!
