It is an excellent and brilliant game. What I liked most was the mechanic of unlocking doors with keys and finding *more* locked doors, which sent me off to search for *more* keys. It was simply magnificent; the "locked door" theme was executed to perfection. I also want to highlight the brilliant storyline—I was particularly surprised when the house started chasing me; that was truly terrifying. Now I’m waiting for the sequel, though this time it should be called "Door."
