I was quite impressed by this game. I think the best part of it was probably how fun it was just to see those guys move. They really were quite fast. I didn't even need to turn the speed up that much. It was nice to have such a wide open space. Then again, that did make it harder to reach your target.
Some of the controls seemed off, but they mostly worked well. I like just seeing them fight. It has the feel of a standard defense game, but is still different. The title could be a tad less generic, though. Ah, I'm just being nitpicky.
