Using Q and E, look at any places where you think a monster might be hiding.
If they haven't already killed you, smiler, run to a light-filled room.
The one monster in Level 2 (Pipe Dreams) basically gives you endless stamina once you exit the dark region, so run and enter the room when you see the rainbow light drift boss .

Attendees should crouch in the corners to avoid being seen by the entity (they won't move or rotate).

Simply avoid the area with the dark piles when playing poolroms.

The End Black Entity: this one is hard; attempt to hug the wall. When the monster is farther away from you, you can walk rather than crouch, but do not run. If the monster is coming toward you, crouch and begin moving to the left or right.

Walkthrough:

Level 0 (Yellow walls): I'm not sure if there are any more spawn sites, but generally speaking, if you spawn at medium-sized pillars, you should turn left or right. Pitfalls are on the left, and an empty room is on the right. The exit will be in one of them.

Level 1 (Underground Parking): As soon as you spawn, hasten to the chamber behind you. Smilers will show up when the lights are turned out. Check the doors while you're in the "secure" chamber; if you find pipes, go inside. (I'm not sure, but the pipe chamber should be in the third room.)

Level 2 (Pipe hallway): After you spawn, move forward (there are two ways to go, but just use common sense as I can't tell you which because you can spawn at different degrees). After you leave the dark part and start hearing sounds, the game will bless you and give you infinity stamina for a while; use it to your own advantage and start running at 200 mph/s; when you see rainbow lights, enter that room. The most painful part is here.

Fun level (obnoxious birthday music): You know what? I won't tell you how to get out of this level because it would take 5 paragraphs; instead, look it up on YouTube.

You basically need to gather all the tapes that are discovered on bookcases to complete Level The End (that dark monster). On the computer in the middle of the room, you may find the remaining tapes. Once you've obtained them all, the monster will vanish, and a computer film will then begin playing, essentially revealing the player's location.

Level 992- I don't know bro, something like 89234892357327859273523 or something like that (a depressing staircase) - All you have to do is reach level 50 and leap off the stairs to end your life. I won't tell you what happens after you jump off since I can and I don't want to give you a spoiler, hahahah.
