I did not care for this that much. I admit that I was a bit motivated to keep on playing. Of course, that was only because there were medals. Anyway, what really ticked me off was how a single guy who came on the ground defeated you. In most defense games, it takes awhile for people to completely destroy you. It just seemed too hard that way. At least it was fun to blow up all those stupid guys.
I wish I could hit those stupid planes more. It's mostly typical military stuff for a game. It isn't bad, it's just okay. I was unsure if there was music in this or not, I must have had the volume up low or something. You could also use more detail as there wasn't a lot in this game.
