Sure, It's a simple game but it was actually fun to play except for some problems:
First add in a graphic of a club swinging back when you move the mouse so you know which way the ball will go.
Second, I would recommend changing the 'mud?' (lose a ball terrain) to a different color (maybe red Lava or just add animation to show it is not dirt) Also, losing a ball because it goes off the top of the screen feels like a cheap trick to punish the player. Did a bird eat it? If you want to limit movement then put a roof on the level.
Third. DO NOT have a maximum stroke limit. I was smiling playing the game when suddenly -game over. too many strokes- Frowning! There is no point to a max stroke limit other than to annoy players. If you have over 4 strokes per hole, you already know you suck at the game. Don't point it out to the player and end their game. just let them have fun playing the levels.
