Wonderful read, Zipp! I like that you reference similar scenes from other games, and also talk about the psychological aspects of the game.
As far as "fleshing it out," I didn't necessarily mean adding a story or making it more complex. I think adding more modes while keeping it simple and surreal would be nice.
As far as story goes, though, the game
kinda has a story already. I think it borrows the concept of collecting notes from the web series Marble Hornets, which is a found-footage web show dealing with a couple college filmmakers who run afoul of Slender Man/The Operator. I'll leave it at that.
