Not a terrible game, way too much space between events though made it break the feeling of suspense and immersion. At the end with the elevator if you tried to go left to the previous rooms you're blocked by an invisible wall which doesn't make sense because you've had something to physically block you from going back I.E. at the beginning when you turn the pipe on and snow falls over the entrance.
Overall I really liked the game concept and think this could be a pretty good series. If it's being released episodically though it needs more content than just 3 minor puzzles
