The dark and depressing mental hospital + unlimited horror dungeons + script-killing core gameplay + God-killing system + innovative counter-routine plots,
Abandoning the traditional thriller game of killing monsters and upgrading, the core is to kill the murderer through the script, restore the truth, tamper with the script, and kill the dungeon god. The mental hospital is the anchor of reality and the most powerful plug-in. The protagonist is a "lucid madman" who is innovative, dungeon-hunting, and logic-burning.
