I Have a Bug in the Rules

When the clock struck midnight, the lights of the Municipal Library went out and on again, and the window outside the window was swallowed up by endless thick fog. Bloody rules appear on the screen, and behind the contradictory regulations is a suffocating death trap. Chen Mo, an ordinary restorer of ancient books, and several strange survivors were forced to get involved in this cold survival game. [Rule 1: Keep quiet, any sound exceeding 50 decibels will attract 'them'...] [Rule 12: There are only eleven rules. Fatally contradictory rules, wandering twisted shadows, malicious "administrators", and the little girl in a red dress looking for her mother... Every choice is a matter of life and death, and every breath may violate a taboo. They must use their wisdom to interpret the rules, find loopholes in desperate situations, and maintain sanity in the midst of madness. However, when they struggled to survive and tried to get in touch with the truth, they discovered that this "echoing space" full of strange rules and rumors had a sad origin and a cold and ruthless "system" hidden behind it. What's even more frightening is that the nightmare does not stop at the end of space. The edges of reality begin to distort, and unexplainable "noises" appear in familiar cities. The "Overseer" follows us everywhere, other "survivor" organizations have their own thoughts, and the system itself... Seems to be learning and evolving. Can you tell whether what echoes is a clue to redemption or a deeper despair? This is a dance on the edge of madness and reason, a race for survival using life to interpret the rules and fight against invisible giants. Hush - stay quiet, the game begins.
