The were 5 'areas', each with around 6-8 stages. Some of them, especially later on, are two parters. That is, you finish one puzzle room, and then there's another puzzle room before it goes to a loading screen for the next stage. It took my brother and I about maybe 7 hours or so to get through the entire co-op mode, with a break for dinner. I didn't time it though, so that might not be quite accurate, and there were two or three puzzle rooms we got stuck on for a while.
