This is not a horror game about things that jump out and scare you. This is a horror game about feeling lost and being worried about dying instantly to what's around the next corner.
This game does not care about what came before or what comes after. There is only the labyrinth.
There are 50 mazes in this labyrinth with a door at the end leading to the next maze.
Your goal is to get to the end of the labyrinth.
There is a Monster on most floors that will kill you with a touch.
Toilets can be used to Save. The area around them is safe from the Monster. Not every floor has one.
Eyes on the walls may or may not alert the Monster to exactly where you are.
There is no reasoning with Monsters. There is no hope but to run.
