In 'Whose There?', you play as an inquisitive detective trapped in a seemingly abandoned mansion during a thunderstorm. As the night progresses, eerie sounds echo through the halls, and rooms rearrange themselves before your very eyes. With nothing but a mysterious notebook that provides cryptic clues and bizarre stories from the mansion's past, you must confront the chilling presence that's stalking you. Solve puzzles, investigate strange occurrences, and uncover the hidden secrets of the mansion that may reveal who—or what—remains trapped within its walls. Will you uncover the truth before it's too late, or will you join the ranks of the mansion's shadows?
