Source facts
What is the primary objective of the game?
The game tasks you with surviving an intense simulation of psychological endurance while trapped in an empty room. You must navigate this isolated environment without any personal belongings, provisions, or human contact to sustain yourself during the experience.
To interact with items in your environment, use the E key on your keyboard. You can also move around the room using the WASD keys and crouch by pressing the C key to navigate the space effectively.
Your only method of connecting to the outside world is through an analog rotary phone provided in the room. This device serves as your sole link while you endure the isolation of the simulation.
