Looking for a markiplier video?

I have been remembering this old video for a while but no matter what I search I can't find it. He was playing a horror maze game where it was very dark and the walls looked like a rusty/bloody color. The games rule was that you couldn't turn around, if you did then the hallway infront of you would become a dead end, turning around again causes you to get trapped in a double dead end, there was some kind of monster also wandering through the halls, I think it was some kid of skull. The goal of the game is obviously to escape and I believe it was a single video and not a series but I can't remember a detail specific enough for a youtube search to find it.
