Ur a backrooms expert right? You have been in the backrooms alot, but if you aren't, may I recommend finding a vent and a ladder to climb asap to go to level 1 as you can't find many resources in level 0, don't worry entities in level 0 are very rare but you may encounter howlers which knows the layout of level 0 but they are not much to worry about since they are rare, I'll meet you in level 1, the habitable zone.
