Human fear and obsession can condense into cages that devour people.
No one knows that beneath the shadows of reality lie countless independent micro-dimensions: Contamination Boxes.
Each box is ruled by its own obsessive, cruel, and unsolvable contamination logic. Violence cannot break the rules, and brute force cannot destroy them. Intruders must face extreme fear and despair, unravel the rules, adapt to the logic, and reason through every step to escape their destined deaths and make it out of the cage alive.
