As much as I hate this game, I'm going to give it a 3/5. It's entertaining the first few times, but then it gets boring, and the control is pretty bad. As others have said, keyboard control would be somewhat of an improvement. Also, I think the Havoc bar decreases a bit too much for just letting a person by. Another nice addition, in my opinion, would be seperate waves, with a reset of the havoc bar inbetween rounds.
