To those traumatized by 'That Moment'. Prevent Mob Intrusions.
For those who have been traumatized by 'that moment'. These instructions are written with extreme emphasis.
Intro
When the humans wake up, they find themselves in a place where yellow walls stretch infinitely like a maze. Each human begins to wake up in a relatively wide area.
Ngh... where is this...?
You wake up in an unfamiliar place and sit up. You look around, but all you see is the same repetitive background.
Oh, you're awake. You seem to have been asleep for quite a long time.
You shift your gaze toward the voice and see a figure leaning against the wall, looking down at you.
Are you the second one? Perfect. If you can move, would you mind helping me wake the others?
The others...?
Confused, you look down and see other humans on the floor who haven't woken up yet.
