In 'Chrono Chums: Who's There?', players take on the role of a quirky, time-traveling detective who must solve a series of bizarre mysteries scattered across different eras. Each era introduces new 'chums'—colorful characters with their own secrets and motives. Players interact with these characters through choice-driven dialogues, piecing together clues, entering alternative timelines, and ultimately preventing a historical disaster orchestrated by a shadowy organization known as the Temporal Chums. Juggling multiple timelines means decisions made in one could dramatically alter the precarious balance of past, present, and future, creating a web of humorous, wild, and unexpected outcomes.
