I played it for my YouTube channel ( Youtube.com/xBuster6 ) and will be uploading the session sometime in the next week or so.
I received a different ending than the commenter ImpactGang. My ending said "there is nothing behind you" and sent me back to level 1 from what I could notice.
ImpactGang's ending was a jump scare type ending.
So there's definitely at least two endings to the game. I'm not sure about if there's more than two.
