In this game, you are in a Manor with about 8 or 10 people and a dog, and you are all being hunted down one by one by a malevolent creature.
Your viewpoint changes dramatically and repeatedly, with each character viewing the environs differently. The actions you can take and the feelings you can have are all so different. It was a great experience.
After a ton of hand holding through different PCs, the game dumps you in a puzzley environment, which throws off the timing of the game. I only got one interesting ending, and not the best, but other reviewers have noted that no endings seemed satisfying.
Still, I recommend this for its atmosphere.
