I played this with my wife, it took us roughly 5 hours to roll credits. We found that the characters were kind of dull and the story was uninspired, once you work out that all of the scary things you're seeing are all a result of the hallucinogenic gas your characters are inhaling, it makes the game a lot less scary and makes the choices a lot easier to make - Oh, there's something attacking me, it's obviously not real so it's probably just one of my other characters attacking me and acting could result in that character dying, I'll just do nothing. In the end, we escaped with all of our characters alive and well and feeling dissatisfied.
