Here's a game after I did played rooms and doors https://www.roblox.com/share?code=03afc6debd7b8e4c9bfc866e72eba907&type=ExperienceDetails&stamp=1767361588367

A-10 (The Void)

A-10 was the first entity to appear in run time it seems appear as looks like goo monster with Multiple arm

do not fall behind because they're killing you If you're fall behind and you'll die

A-40 (shells)

A-40 are gray humanoid entity with dragon-like head who only appear in "locker" if player open this locker and they'll either fatal damaging them or scare them without any damage

Similar to Jack from doors as they're appear in locker and scaring them when they open the locker however, they also help entity to attack/kill them by stop player(s) for hiding and entity coming to close until killing them

A-50 (the darkness)

A-50 is entity inspired by hide entity from doors, it is only appear in all hiding spot (except for table)

It will attack the player if they're hiding for too long or if you're late to get out of it and A-50 was almost close to you just You'll lost your health

A message will appearing and say "something is in here" when it is appearing after hiding for too long

A-60 (multi-monster)

A-60 is one of dangerous entity who first appear in start location was room with Multiple locker and yellow word "HIDE" on right wall

Player can understand by hearing "sound" it's means a-60 was spawned before coming to attack and player must be survive against them by go to hiding spot

A-60 has "chance of spawning" which meaning that entity can spawning at any time and not spawning when player opening the door of next room unlike any Rush-like entity from Doors

However, it has prime version of A-60 called A-60' also known as prime multi-monster who only spawning after A-60 spawned and appearing in dark rooms

A-90 (Paralysis)

As we already know this is entity with same name and mechanic this is version of A-90 from doors but few different is a-90 named "Paralysis" and its appearance looks similar but difference. It was called "paralysis" but in original. It wasn't called Paralysis anymore

It will appear on screen before attack. If player moved then A-90 will harming them

A-100 (prevmia)

A-100 (prevmia) is flying skull that appearing in next room and laughing sounds can be hear

After opening the doors, it will starting attack them when player either turn flashlight on or running for making noise however, player need to hurry up or can kill A-100 by opening locker if they close to it

A-120 (happy Scribble)

A drawing-like face entity, after player opening 120 rooms, it coming and same sound from doors counterpart. The player can running away and find out the hiding spot when it spawned and coming to attack

A-50 (the darkness) doesn't attack the player until A-500 room just however, safe spot and table cannot keep you safe from that entity

A-200 (inside)

A-200 is different and separate entity looks similar resembling A-120 but few different with that white fog. It is only entity who can instantly kill player(s) and is very quieter and always spawning at any time

After entering A-200 rooms, Players must quickly hide just get out and then re-enter it when it is rebounding

Player also can hearing a sound of that entity despawn

I'm finished to say it but that's not post about their behavior anymore that's info about entities identity who they are
