Exception Space 404

Core horror elements: There are "abnormal spaces" in the city - house numbers that do not exist in reality, blank areas on the map, and extra floors late at night. Those who enter will encounter a death game with "weird rules", and survivors will gain "permissions" to distort reality. World view: The world is like an old server, with "404 errors" occasionally appearing - those 404 spaces are loopholes in the system, and monsters called "garbled codes" inhabit them.
