Combined with the hints from the Ludum Dare comments, we have: B _ _ R _ _ _ _ _ _ _ _ _ _ _ _ _ _ O _ _ M _ _ _
With me :B _ _ R _ _ _ _ _ _ _ _ _ _ R _ _ _ O _ _ M _ _ _ If I'm not mistaken.
That R isn't supposed to be in that position :/
Maybe, I tried to replay it (I understood many more riddles) but I'm forever stuck on "This is not supposed to show up".
Oh no that's a shame D: Do you happen to remember what the riddle prior to that message is?
