CO-LLAB-OR-ATION! I love co-op story games! And such wonderful levels as well.

I played with my sister over the holidays. She doesn't really play action games, so there were some platforming mishaps. The boss levels are methodical and I was immediately concerned that we wouldn't be able to do them. But my sister is a boss herself and we got through them really well. I underestimate her, and she kicks my butt at almost all the minigames. Jokes on me.
