Kraven Manor is a first-person survival horror game on Steam. It has puzzles and scary house exploration. We liked the Seventh Guest, we liked Amnesia, so we bought the game (on sale for $1.97 through January 2) and gave it a spin.
First, we explored the library, which seemed like it was having an identity crisis and wanted to be a hedge maze. Then, we explored the wine cellar, and tried desperately to break stuff by tossing it around the room, because that's how we roll. Then, we were killed. We think we were killed by a statue, but we're not even sure about that. Whatever it was, we screamed, so mission accomplished, game.
