We have played one and are nearly finished with our second 2-player campaign and so far the heroes have been having a rough go at it. On some quests it was poor choices, on some it was bad rolls, and on the rest it just seemed that the heroes were outnumbered. The second encounter in "The Twin Idols" quest stands out for me as it was the last quest we did last night. It plays out like a game of capture the flag and both sides were just pushing the other side back then they were being defeated and the process repeated itself until we finally decided to call it quits since it would have taken hours longer to resolve. I'm sure if a side managed to get really good rolls on a turn it would change quickly but so far 2-player games seem to be very difficult and the slightest mistake or bad roll can end in defeat for the heroes. It's very scary.
