This game just drove me nuts! It wasn't so much that it was hard, it's that I couldn't tell when I was winning a medal! Okay, not to make this personal, but I stayed to play this game while my mom was putting Christmas stuff away and she went insane because I wasn't helping! I have to give you credit for making an addictive game. I managed to get far as beating the first part of story mode.
I KNEW I got a medal for surviving in Chaos Mode for over a minute and then nothing happened. I guess it'll show up eventually. I liked the different designs for all the enemies. It's amazing how this just goes on forever. You are certainly creative.
