This is such a funny idea, I love it! Controls were very smooth, the idea was very clear, and overall the game was intuitive and enjoyable! The only thing I wish was that there had been something more to it after a while. Maybe "environmental" shenanigans (e.g., squirrels or rabbits chewing up the "course", reducing playable space, or golf carts "driving" over previously at-rest balls to make more chaos)?
Either way, you've got a great, addicting game on your hands, good work (:
