The Floorroom.exe was some weird game that I found, it featured different characters and sans was one of them. Basically you would wander around a underground facility seeing these characters in the shadows constantly. Sometimes you could interact with them ( but some of the text was in code, or you couldn't read it at all ) and other times you had to escape from them. In the end you realize that you've been seeing hallucinations the entire time. But the game no longer is there.
