Thanks for your submission! Feedback from the judges: 

1. A simple concept, well-executed, self-explanatory. The reflection theme is there. I was unsure of aiming at first, because the green circle seemed to stay on the ball, but I soon figured out that that pointed to the goal, not where I was going to strike the ball.

2.  Following the ball as it rolled through the city was nice and relaxing, but it eventually got stuck in a corner.
