This is a case where a ghost story was written based on a strangely taken photo, and the ghost story became a worldview.Lol
I thought it was similar to SCP in many ways.
Part of the worldview created by a group of people, and each room is given a name to describe the characteristics...
I think the result of organizing the worldview and setting like this and gathering many people is very attractive.
I thought that the concept of the back room was unique and good, that it is a room where errors occur and fall like a game in reality.
There is a spooky charm of a bizarre room structure.
