Interesting blend of dice and golf. I like the way you can 'choose' the modifier on your next shot by tapping it gently to one side or the other.
Improvements could include the ability to preview the course and rotate the view, so you could plan your shots better. Maybe the preview line should follow the ground too - when it intersects with an uphill section it quickly goes out of sight. Also, if the dice stops behind or under something, it'd be good to have a sort of ghost outline to show you where it is. These are fairly minor niggles though.
The main problem is that it's quite random! The dice is quite unpredictable, even when there's no modifiers. I found myself having to use full strength quite a lot just to make up the distance, and even from the tee with no modifiers things like the thin bridge in one of the later holes is a very sensitive shot. Also, the way dice tend to stop moving suddenly makes positional shots a bit more sensitive to power than is ideal. I would try to move the dice one side over and succeed, but to roll it say 3 faces would be nearly impossible.
Well done for creating a fun, working, good looking game in 2 days. Not an easy feat!
