This is an extremely inventive, wonderfully artistic, thoughtful and entertaining game.  It defies most of the norms as to what one would normally expect out a game, but it's perfect for what it is trying to be.  It's suspenseful, engaging, and evocative.  The writing is superb, the tables have variety, wit, and creativity seeping from the very walls of the abandoned corridors.  This game is so much fun.  You owe it to yourself to try it out.
