◆ A Box With No Purpose. Over 15,000 Possible Interactions.
You wake up in an unfamiliar mansion.
Your body is strapped to a chair. Only your hands are free.
In front of you sits a strange box, covered in buttons, levers, and mysterious mechanisms.
What is this box? Why does it exist? Why are you here?
You have no answers.
One thing is certain.
Whatever is in front of you... you can touch it.
Pick it up. Rotate it. Press a button. Pull a lever. Watch carefully.
Every action produces a reaction. Or perhaps... no reaction at all.
What does each interaction do? How can it be used?
Through observation, experimentation, and persistence, you'll gradually uncover both the secrets of the box and the truth hidden within the room.
◆ There Is No Manual.
But you are not without clues.
Something can be pressed. Something can be moved. Something lights up. Some reactions feel strangely familiar.
Everything you see is a clue.
Even an interaction that appears to do nothing may become meaningful later.
A familiar response may reveal an entirely different purpose when combined with something else.
Observe. Take notes. Experiment.
No one will teach you how this box works.
Discover it yourself.
