Mists of Aiden is a horror adventure game with a first-person view. You play as a young thief who decides to steal a rare jewel from a remote estate. It was relatively easy to get here, but there were problems with escaping — the house is not going to let the unlucky thief go. Each attempt to escape will feel different — there are five stories and five nightmares, a huge mansion with dozens of rooms to explore, puzzles and riddles.
