Players take control of the lighthouse keeper to find out the truth. You wake up in the lighthouse keeper’s house, a familiar lighthouse, a constant job that was supposed to be another regular shift. But felt a deep concern, and there was no more peace on the island. The world is guided by the right path, suffering from the oppression of reality or psychological influence, gradually doubting themselves, along with thoughts, gradually rewriting their own lives.
