ドント・ノック・トワイス/ Don't Knock Twice

Don't Knock Twice is a single-player first-person survival horror game with support for virtual reality headsets. The player explores a large manor house in search of a missing daughter, interacting with almost every object and following hints delivered through an in-game mobile phone. A demonic witch can appear without warning at any point, keeping the player under constant threat. Light combat and item elements are included, such as using an axe on doors and combining objects into makeshift tools. It shares its name with, and is loosely based on, the film of the same title.

The player takes the role of Jessica, a guilt-ridden mother and artist whose relationship with her daughter Chloe has become estranged. Drawn into a frightening urban legend about a vengeful, demonic witch rooted in Slavic folklore, Jessica must uncover the truth behind the tale in order to save her daughter. The search leads her through a foreboding manor house, where the presence tied to the legend can strike at any moment. What begins as a mother's desperate attempt to reconnect becomes a fight to understand and survive the horror surrounding her.
