Surface is a first person linear exploration game.
In this game you simply walk your way to the end. The point is to immerse yourself in this world presented to you.
There are no mechanics besides movement and looking around.
Being mysterious by design the story isn't told explicitly, everything is up to interpretation, all you know is that you want to reach the surface.
While the game does not contain monsters, the ambience and environments will invoke feelings of unease and even dread.
Every sound, model and script was crafted by me.
You have lived since birth in remote region of the megastructure, its not clear anymore how vast are its borders, you just want to see the surface once.
