The Stairwell

The Stairwell is a first person horror game made by EZeddy that is losely based off of SCP-087's document.

Gameplay
The player returns to the childhood home and discovers that there is a mysterious staircase that he has never seen before. The floors in the game are not the same - on the landings you can see puddles, holes in the walls, power supply panels (I wonder what they do there?) And other elements and a hallway at floor 45. The game is replete with screamers, so be careful.
