On level 2, I played for almost an hour, only to have the very last group seem to run past my men and traps almost unscathed because they regen so fast. I end up losing the map and have absolutely nothing to show for it. I like the concept of the game and the style, but I think I'm done with it after that.
I just changed from one character to another once I realized I'd have a warrior class guy with me, and Rogan is referring to me by the old char's name.
Two warriors can be super powerful!
