Agree Disagree

I love it.

Great expansion co-op play with challenging levels that finally require you to use your head. Its "nice" to see people failing to get the puzzles from what I recall often, to the point of having to hand hold them when they play with you. I don't agree that its freaking hard its just challenging. Too bad some levels were cut from it though.
