Curious: anything known about mouse swing yet?
I've been testing using the mouse swing and am loving it. Your swing tempo, along with swing path, determines how straight and far your shot will go, negating any real advantage to using a straight edge. If your tempo is off you will find your shots going left or right regardless of how straight your swing path was. If your swing path is off you will find your shots going left or right regardless of how good your tempo was. As Ben Hogan liked to say "you can only hit a ball straight by accident" and this applies to this game, especially at its' most difficult level.
At its' most difficult level, it is very difficult - as it should be. Swing tempo is critical and at that level if your tempo is off you will be spraying the ball all over the course.
However, when you do "groove" your tempo and can keep your focus and concentration you can break 90! Shooting par at this level will be a definite accomplishment.
There are 2 different difficulty level controls with 4 settings each that players can tweak to find the difficulty level that best suits their desired level of challenge within the game.
