Overview

Lost Item plunges players into the disorienting reality of a late-night office building. Waking with no memory of how they arrived or how long they've been there, the player is guided only by a cryptic note: "Patrol all the way to the 10th floor, flawlessly." and "When you find Lost Items, pick up every one and place them in the collection box." This sets the stage for a tense, atmospheric experience where meticulous observation and adherence to instructions are paramount. The core gameplay loop involves navigating the building, searching for a specific number of 'Lost Items,' and returning them to a collection box. However, the task is far from simple; missing even a single item resets the player to the first floor, forcing a painstaking restart. Furthermore, the act of collecting these items can trigger unsettling paranormal phenomena, adding a layer of psychological dread to the exploration.
