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.

Recommended Oct 7, 2023

I think this game is alright but the checkpoints need work. Not a fan of redoing a section just coz of a silly game mechanic (keypad inputs). I do appreciate that it has voice actin'. Played for about an hour and that's not bad for 5 bucks. The game has to be beaten in one session so I hope ya have the time to spare to get those multiple endings. Gameplay here: https://youtu.be/zV5CILJK4Y8

A beautiful game with an interesting story. I really enjoyed the premise of having to take photos and exploring the castle while we did so. It looks fantastic, the voice acting was great. Overall, thoroughly enjoyable. I'll definitely be playing again to see if I can get those different endings. I would definitely love to see a full length version of this game!! My play through is here: https://www.youtube.com/watch?v=Nm5iEAbyHQ4

This game looks fantastic so far! I haven't finished it yet but I'm already impressed by the visuals and a little bit spooked by the little jumpscares ;) Edit: I just finished the game and it was amazing! Hopefully, more people will know about this indie game in the future :D
