Looks like a fun take on golfing games, but it isn't executed very well.
Thing that bothered me the most is that the physics aren't correct. The red ball always moves in a straight line, swinging the blue ball haphazardly around it. Give both balls momentum and apply a force on each towards the other corresponding to their distance from each other.
It's also infuriating the way the blue ball swings around as you're trying to shoot - this absolutely must be fixed. Using the mouse is near impossible because the game takes away your cursor.
