Exit 8 is cinema for the livestreaming era

The rules of Exit 8, both the cult indie game and the recent film adaptation, are simple: You're stuck in a subway station that loops around endlessly. If you notice any anomalies on your current loop, you turn around. If everything is the same, you keep going forward. Each successful guess takes you to a new entrance where the loop recurs, until you reach the end of the labyrinth, Exit 8 itself.
