Level 1 is the second level of
The Backrooms and is made to resemble an empty warehouse.
Even
doe it's named "Habitable Zone" not a lot of entities are present within the level, and this level is also the entrance to The Hub and is also a good place to
get items, as the items are in crates that can be found throughout the level.
And it isn't really that complicated to escape this level either, as it is pretty much similar to Level 0.
