I just started playing a few days ago. now i am hooked. I can't get credits for new equipment fast enough. lol.
Here is my suggestion.
Have variable random length shot meters, if not from one hole to the next, then from round to round. If the meter is 4 inches on one hole, it may be 4.5 inches on the next. Regardless, if you need to hit with 50% power, then the timing of your mouse click will be different from hole to hole (round to round). It will keep the auto click cheats out of the game. (if there is a visual external auto click cheat, then slightly change the location of the meter as well)
If using the above suggestion for round to round, then maybe you can allow players to go to the practice tee/green for1 minute before the round starts to get used to the meter that would be used for that round.
I think this will add a new dimension to the game and keep the montonous same click-click timing out of the game.
