You wake in a locked prison cell. Everything around you is red. A mirror on the wall shows you something true when you look into it. The cell unlocks — but freedom is not what waits on the other side. Explore a non-linear world with interconnected level design, each space stranger and more dream-like than the one before. Speak to the NPCs you find, or kill them. Read the signs posted on the walls, or ignore them entirely. Follow the route that has been laid out for you, or find another. Be made to read scripture against your will. Work out what it means that it means nothing. Worry about someone else's mental health. Come to terms with the fact that there is nothing you can do for them.
