In 'Hello, Who's There?', players step into the shoes of Casey, a quirky detective known for their unorthodox methods. Set in a bustling city on a stormy night, a series of mysterious phone calls interrupt Casey's dinner. Each call introduces a new character—witnesses, suspects, and even pranksters—all with tangled stories and hidden motives. Using interactive dialogue trees, players must discern truth from deception, uncover secrets, and navigate the chaos of a night that unravels a conspiracy far deeper than a mere dinner interruption. Will you solve the case before the clock strikes midnight?
