Psychological Horror ADV Smartphone Steam Store Page Opens
Developer OwataStudio opened the Steam store page for its psychological horror adventure game 'Smartphone' on July 21, 2026. The game, originally released for browsers on unityroom on May 13, 2026, is being remade for PC via Steam. In 'Smartphone', protagonist Shinya Komatsu wakes up trapped in a dark, unfamiliar locked room with no memory of how he got there. The only object available is a smartphone, which players must operate to search for clues and escape. The Steam version revises the story, presentation, and controls compared to the browser original. While content up to ending 5 remains the same, the remake doubles the number of endings and adds new developments and conclusions. New apps not present in the browser version have also been added. The game is scheduled for release approximately one month from the store page opening. The browser version remains available for free on unityroom.
