I do like this game, but there is a big problem with it. I don't like having to command all those different machines. I would have liked it if they were automatic. Yeah, I guess that would have been a bit too easy. I'm just not used to seeing this in a defense game. The music is quite good as well.
Sometimes, I just kept clicking above me to destroy below enemies. The graphics are fairly decent. The title's pretty cool too. You certainly get your money's worth. It's worth checking out.
