Bought this a short time ago and I LOVE IT.
Ball physics work really well, sound & graphics are great and although I've only played 2 Trophies so far, the courses seem varied enough to give a decent challenge.
The one thing I would like to see, is a detachment of movement and ball power. At the moment they're connected, so when you want to set power after getting the angle/direction you want, the direction is still moveable, so you have to do both at the same time, using mouse & keyboard at least, not sure about joypad, haven't tried it. I find this a little distracting, but it's not a game-breaker, it's still great fun :-).
If you like crazy golf, which I do, you will probably really enjoy this. I'm off to have a go at another trophy now ;-).
