My group played it several nights ago and had fun. We played through scenario 2 and 3, but failed the 4th. We learned that we should not be stingy with spending the XP to remove Effect cards, especially environment cards.
Some of the cards were worded strangely - referring to things "closest to you" then referring to "the character". We randomly rolled who a monster would attack if multiple characters were equally distant, but as the time went on we just picked who would be the most efficient for the group. We also placed them on each tile wherever we wanted.
We enjoyed it enough that some of the players, myself included, wished that there were more levels to play through like Warhammer Quest.
