Leaderboard Golf

I am on Vista, not XP but this shouldn't be a problem. I was unable to really try the game because I could not even start to get the golfer to hit the ball.
Some keyboard things I tried were Enter, Space and just about every other key on the keyboard after that. Thinking it might have to be a mouse I came unstuck as the mouse was just locked on to the direction for the ball and that is all it would do. Right clicking the mouse also did nothing.
It seems the risk of buying the game is not worth it to see if everything might suddenly work in the paid version so for me that is never going to happen. I don't mind if a trial version comes with a readme file explaining a list of limitations which will be fixed after payment but this game is doomed to fail due to a lack of interest from the author.
