Great game, especially considering its free!
The controls to start with are good. You almost only use the mouse to play the game, which sounds a bit hard, but its really simple to play. It makes learning to play much easier than your average football game (not that they're very hard). And although its easy to learn to play with, I don't find myself winning every game I play. The difficulty is balanced very well. The controls aren't perfect and could do with a little bit of polishing off, but they're are very good.
The gameplay is exactly the same to the Fifa games that you would buy for £30 from a shop, only its free. The graphics aren't quite as good but then its much smaller.
Overall I'm very impressed with this game
