11F

"11F" is a horror, mystery, and adventure game where you explore a building called "The Origin" to reach the 11th floor, which doesn't exist. After your father's funeral, you receive a real estate rights transfer certificate and a note addressed to you, prompting you to visit the building. As you progress through over 20 themed rooms filled with ghosts, you uncover the lives and sufferings of the residents, ultimately facing the mystery on the 11th floor.
