The Last Door is one of the best horror games I have played in some time, though its short length and episodic format tends to break the mood. Creepy art, unsettling music and disturbing characters create a memorably scary experience. Puzzles are challenging, but rarely difficult, and the mysterious story will keep you hooked. Try it for free on browser first, then nab that improved collector's edition on Steam if it strikes your fancy.
