When it comes to tower defense games, I usually easily lose appeal to the game. However, this version of defense was actually REALLY entertaining. I'm giving it a 5/5.
I love the fact that the Hero's Boss always seems to find communication, tells me what he's planning, and there's always an awesome way to counterattack. :D
