besides being rediculously easy to beat.....
I loved it. The only thing that got to me was how incredibly easy all of them were to beat. I love them all, dont get me wrong, but perhaps giving the computer opponent a bit of an edge might be in order.
Other than that, i loved it. Extremely fun games, all of them, and the addition of ooodles of turrets makes for some interesting matches.
Also, a button of some sort to automatically upgrade all turrets would be nice.
