Nice little billiard puzzle.
More ways to control (like being able to reduce the launching force, or to remove the cat from the board) would greatly improve the experience. Many times I was just bouncing around for the last 2 bottles when the front enemy had 3 HP left, meaning that just after the field reset I had to waste all the bottles just to finish that lowlife thug :<
The rolling physics is really cool, well done putting a game out of it!
