I've seen a couple variants on this idea, but this is probably the best one ive seen so far. The rendering is great, and the concept is brilliant. Playing the hole where it lies was a good choice, as it lets you move closer to the ball on the trickier maps. I only wish the ground had more friction so the ball would stop sooner, and I would love to try a version where the hole was itself controlled like a golf ball.
High marks, I want to see more.
