I'm generally not one to play horror games. They often come across as formulaic and rehash the same mechanics. I wouldn't say this title is any different but given the scale of the project it still works really well. In a short amount of time the dev tells the story of the how and the why while slowly introducing the feeling of dread.
It does play out a little bit in the standard 'Horror' way. You can expect jump scares and high tension sections. Yet it never feels forced or that the map has been made and populated just because.
Overall, it's outside my general wheelhouse but a solid title that's worth a play-through for anyone that enjoys the genre.
