Man, I read some of the bad reviews (very few), those people suck. This game is not impossible, it's the shit! The fact that you used a point system instead of the traditional stroke system makes it even better. You can still get point even though you're at a +30 bogey. It's great!
People with a short attention span would hate this game, and stupid people would call it impossible since they don't get the whole "gravity" thing, you really need to make a sequel!
Yes it takes a little practice and good luck, but overall I really enjoyed playing it. I came out with 27,405,200 points, don't know if that's good. The only complaint I would have is the screen size, but that's not your fault. It would be cool to play a game like this on a really big screen with bigger courses.
I found this game easy enough to be fun, but hard enough to keep interest levels high.
Great work, and please make a sequel!
