Nightmare Hotel

At the beginning, you dissect a strange corpse and then fall asleep, entering a world full of strange things, the "Nightmare World". If you die here, you will also be brain-dead in reality. If you want to get out, the stone tablet in the hotel has rules. Twelve-level dungeons are more terrifying each time. Everyone must complete twelve dungeon missions. In the end, kill your closest relatives in this world to leave this place completely.
