Interesting... You got out of bounds somehow! Ideally you should just die and go back to whatever room you were previously in, but I guess it just decided to eat you for whatever reason! I'll look into it! Thank you!
In case you didn't yet track down this issue, it's in the room Hurry Up. If you hit the ceiling you end up in a room titled "Separated" but with nothing but darkness. It seems you must quit and reload the game to escape.
