I found a couple bugs while playing. First, the flipper bug. You already know about that one. Second, one of the times I played the ball got stuck in the launch ramp. The ball got to the top and the blocker thing knocked it back down and trapped it in there. I had to restart. Third, and this may or may not be a bug, when you have multiple balls in play, the balls don't bounce off each other. Instead they just go through each other. I tried posting this in the actual game comments but I had already posted a comment there and apparently you aren't allowed to post more then one.
