In 'Chrono Chums: Who's There?', you step into the role of Timmy Timekeeper, an eccentric young inventor who creates a device that inadvertently opens portals to alternate timelines. Navigating through bizarre historical moments, you gather quirky companions from different eras—like a sultry flapper from the '20s, a rebellious knight, and a disco-loving caveman! The challenge lies not only in solving humorous and dramatic dilemmas within each timeline but also in piecing together the clues of a larger mystery that threatens all timelines. Engage in witty conversations and team dynamics as your choices significantly affect both the timeline you're in and the fates of your whimsical companions.
