I was a little confused about how to start (looking at the scripts helped out here), but once I did get started I had to slowly spawn the balls because they deleted each other when they collided. But once I got started and got the hang of the controls I appreciated the feel of the paddles - the joints really make a huge difference compared to trying to do transform-based rotations. So that's a remarkable aspect - you figured out how to get joints working even though we didn't talk about them in class. As others have mentioned, the color scheme is also consistent and appealing. Also really nice use of user-define axes to make your paddle control script generalizable.
