The camera is another issue - it isn't really mobile, so other than the opening fly-by of every hole, you can't adjust your viewpoint at all. This creates some major problems on certain holes, making it nigh-impossible to actually aim your shot, which is obviously a fairly important aspect of any golf game. The learning curve on the power meter is rather steep, as well, but as with anything, practice will generally alleviate any problems there.
3D Ultra Mini Golf Adventures is a generic mini golf game with a few redeeming traits. If you can get past the poor physics – or at least accept them – and you plan to play almost exclusively multiplayer, it’s decent. Otherwise, it’s not really worth your 10 bucks.
