About This Game

When you woke up, you found yourself trapped in the corridor of a deserted multi-tenant building.

An impersonal space stretching on endlessly. Countless surveillance cameras. And red-circled ‘No Entry’ signs posted everywhere.

The notices read as follows:

・You must [strictly adhere to] the instructions on the red-circled signs under any circumstances.
・Find the lift and go down to a lower floor.
・Escape from this building.

In this building, the rules are everything.

Violations are not tolerated.

[Violation = Death]

Your objective is to explore the building whilst adhering to the instructions on the prohibition signs, use the lift to descend to the lower floors, and aim to escape. However, the building is filled with various enemies and traps. At times, you must determine the correct path to take; at others, you must avoid danger.

Use your powers of observation, memory and judgement to survive.
