Well, this seemed to be basically the same as the other games. Then again, I didn't go that far. I wasn't that motivated. Still, there's nothing at all wrong with this. It does give the same experience as the other games. I'm surprised at how hard it got.
Maybe I've just gotten rusty. I thought it would be a lot easier! Well, it was still very playable. Defense games are easily addictive. I just wanted something new.
