In 'Hello, Who's There?', you play as Alex, a weary detective summoned to investigate a long-abandoned mansion rumored to be haunted by its last resident, a reclusive author who vanished without a trace over two decades ago. As you uncover clues through interactive dialogue and immersive choices, you begin to encounter strange phenomena—whispers echoing through the halls, ghostly silhouettes lurking in the shadows, and cryptic messages left by the author. The twist? Each success or failure alters the mansion's design and the mysteries surrounding it, and as the storytelling and atmosphere evolve, you must decide who—or what—you can trust. Will you unearth the secrets of the past or become another lost soul within the mansion’s walls?
