Class 0: Safe, Secure, No documented entities

Level 354 is the 355th level of the backrooms.

Description:
Level 354 Seems to be many rooms in one straight line across from another, with a code-lock door between each room. Every room looks the same (With white painted walls and office-like floors and ceilings) except for the shape of the room, which can vary from having the next door directly after the first door all the way to being whole apartments in size. There are no lights in the level, yet somehow it stays lit. It is unknown if the level goes on forever.

Every door has its own code, and there is a clue for the doors code on the room before the door. Currently only the 10 first doors has been succesfully opened, and for each door they cracked the code for there has been something more and more valuable. After the 10th door the room was filled with simular lootboxes as level 1.

Dont try to brute-force the code, as attempting the code too many times causes the code-pad to explode, pontentioally killing the person putting in the code. The code-pad that exploded will replace itself within 5 minutes. Some doors have been broken open instead of being unlocked. How or why this was done is unknown.

If you wish to try to figure out a code by yourself, heres a few things that worked as the code on previous rooms:
*The previous rooms volume in cm^3
*Morse code in slight buzzing noises behind walls
*Number of tiles on the floor that are cracked * the level number

Entities:
There has been no found entities on this level

Entrances:
Find a codelocked door in level 356, Enter 354 on the lock. If it doesnt work, find another door and try again.

Exits:
Leave through the same door you came in through to be sent back to level 356. There is a rumor that there is an exit after the last door. If this is true is unknown
