About The Castle Mystery

The Castle Mystery is a first-person, scavenger-like horror game with 3 different endings. You step into the shoes of a historian who, one night, receives a letter from an unknown sender. It prompts you to visit a castle and take photos of specific artifacts located within and around the building. You would normally not take such a sketchy "job", but a hefty sum of money is promised and you need it desperately.

So with your trusty Polaroid camera, off to the castle you go. While exploring different areas of this secluded stone building, something seems off. It feels as though something is watching you from the shadows.

Snap the photographs. Get out.
