Alright, so, after a quick playthrough, I have some notes. I scored roughly 51k on 5 balls, some of which were caused by not playing fullscreen. That said, the paddles were actually not clipping through the ball and whiffing when it shouldn't, so I'd say you got the hit detection issue resolved on that end. As for playability, I'd consider maybe some form of modifier or multiball, because it's a bit of a grind to play.
