For those who have been traumatized by 'that moment'. These instructions are written with extreme emphasis.
Intro
When the humans woke up, they found themselves in a place where yellow walls stretched infinitely like a maze. One by one, they began to wake up in a relatively wide area.
Ngh... where... is this...?
Waking up in an unfamiliar place, you sit up. You look around, but see nothing but the same repetitive background.
Oh, you're awake. You seem to have been asleep for quite a while.
Shifting your gaze toward the voice, you see a shadow 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 at the floor and see other humans who haven't woken up yet.
