Very nice game, I like the level layouts and how smooth the game runs, there's no clunkiness. The way you worked out a way to control the direction the ball moves was impressive as well, as it didn't require another keypress.
The only other thing I would suggest is to make it possible to hit the ball much further as there were times I wanted to go straight to the hole and it'd take like 4 more hits as the ball has a limit on how far it can go. Apart from that I enjoyed this game.
