As the author states: "Click left or right of the screen to go next/previous page of the lore, gallery, and extra document. You woke up in this strange office hallway with yellow wall paper, you couldn't recall how you got here, but the last thing you remember is you clip through the ground. You start walking around and see different furniture and some black stuff on the ground, the light buzzing very loud that makes you lost directions. Suddenly, you heard a scream in the next corridor, it sounds like human, but slightly different. As you approach the scream, the source of it wasn't human... it was a dark deamon"
