There are some great interactions in this game! I think my favorite is when I had the money racket and the horizontal moving ball, and I would just hover on the goal line right above the ball. It would cause it to hover back and forth over the goal line since it couldn't reach the racket, which was quite amusing! The black hole racket is quite powerful as well for making the ball do circles over the goal. The bounce physics were a little off though, sometimes hitting the ball with the racket would cause it to slow all the way down. I had fun with this one!
