In 'Hello, Whose Ghost Is It Anyway?', you step into the shoes of a quirky medium with a knack for getting into ridiculous situations. After a minor mix-up during a séance, you accidentally bind yourself to the spirits of five eccentric characters from different eras. To free yourself (and them), you must navigate bizarre encounters in a haunted theater, solve amusing mysteries tied to each ghost's unfinished business, and perform comedic interactions to keep the spirits entertained. Each ghost has skills, quirks, and challenges that can help or hinder your progress, leading to multiple endings based on your choices.
