In 'Whose Call is This?', players step into the eccentric shoes of a stubborn detective who receives a series of mysterious phone calls from unknown figures claiming to be witnesses to a high-stakes heist. The twist? Each caller has a wildly different perspective, some are trying to help, others are leading you astray, and one might even be the thief themselves looking to mislead you off their trail. You must navigate through their stories, choices, and motives while piecing together the truth behind the heist, unraveling a web of deceit and unexpected alliances. The game features branching narratives and real-time phone call interactions that change based on your choices, leading to multiple endings and a unique experience each time you play.
