Probably about 75% through the game.
It's an enjoyable one of those these type of games where you walk around in a museum world and discover what happened. I think nearly all of these games are roughly the same and the only real difference is the quality and immersiveness of the story. The gameplay is mostly puzzle solving and in this case playing hide and seek with monsters. So nothing exceptional in that area.
This one is solid in the immersive aspects as its a decent little sci-fi story and most nerds who are into that will be into this. The same general warnings apply. This is a game will you blow through in an evening or two so its better to wait for a sale but like I said, I think its a good one of these type of games. Not especially scary but more slightly weird and slightly artsy meets intellectual.
