Got to hole 9, but struggled really hard to shoot nearly straight up through the fan thing.
Overall, wonderful game, love the sound track and golf games are always a lot of fun!
Some recommendations: Get the music to just keep looping instead of restarting (minor, but noticeable). I believe there are borders around each level, but perhaps the camera wasn't showing them, but make sure you can't lose your ball. Slow down the fan (?) things. Perhaps find a different way to represent power for the ball, sometimes it was really hard (especially vertically) to get enough power. Maybe create a green --> yellow --> red transition based on how far back you're pulling to max it out. It shouldn't take up 100% of the vertical space to get a max power shot. I believe your calculations cause more pixels to have an advantage!
