Trivia
- First noticed by YouTuber Skelux, there is an identical, mirrored copy of the room's geometry hidden behind the camera,[1] which some have theorized to be left over from an unused feature or additional challenge in the level. Using a spinthrow clip found by glitch hunter GamesJam, it is possible to clip out of the level and carefully traverse around it half-bounds to reach the unused room.[2] However, since the camera position in the level is fixed, it will not be possible to actually see the unused room in an unmodified version of the game.
