Level 289:

Level 289, formerly Level -2, is the 290th level in BackRooms 2D but is the 18th game in the series. Level 289 consists of three areas, The pool, The hall of dull flames and The abyss and has the most areas out of any level.

The pool:

The pool is the first area of Level 289 and consists of a dark basement flooded with dirty almond water. It contains one entity, Screamers, humanoids with no face but a mouth and screams at people to reverse time. The pool contains the exit to The hall of dull flames, this exit being a blue hallway.

The hall of dull flames:

The hall of dull flames(shortened to THDF) is a hallway with blue lanterns, containing no entities and the exit to The abyss, this exit being a black hallway.

The abyss:

The abyss is a void-like area containing only a floor and kitchen items with a black void as walls and a roof. The only exit here leads to Level 14, the exit being a staircase.

Entrances and exits:

You are able to enter by going trough a door on Level 287 with a sticky note saying "swim with the fish" and you are able to exit via staircases in every area that lead to Level 14.
