I usually hate tower defense games, but I kinda like this one. It adds things the others don't have like a movable character and better graphics. Any complaints people have should be the same complaints any tower defense game has. They're all boring, long, and usually very hard.
10 wasn't that bad, but the game is really good. It's incredibly inovative and original. Sure the music is weird, but it compliments the game. My only complaint is the instructions. It's not my favorite, but I have to give it a 5/5.
