Glad you enjoyed it. The rotating 2D camera is certainly a polarizing feature - playtesters either loved it or hated it. I also had an implementation with no rotating camera (which you can try out in the settings) - I find that even harder to play with though. I definitely prefer playing with a gamepad.
Yeah avoiding the ball in certain situations is definitely intentional. There is an exploit here that I never got around to fixing where you get the ball trapped in the I-beam and let it bounce forever, accruing points.
Thank you for the feedback!
