Westwich Castle will certainly remind you of the first Ammesia game by Frictional Games. This is indeed a great presentation, and one that you absolutely have to try, if you enjoy a creepy and eerie atmosphere. The castle, although not gigantic, can give a labyrinthine sense of grandeur, where each room hides a dark secret waiting to jump on you. Recommended, as are all this devs games.
