I like the concept. It's fun. Feedback:

1. The ball seems a bit soft. I suggest you get a real golf ball and putter and see how they behave, if you haven't already.

2. It would be nice if the camera positioned automatically so that it's roughly in the direction the ball should go on the next shot.

3. There were a bunch of flying yellow blobs. I was not sure what they were supposed to be.
