In 'Chrono Chums: Who's There?', players take on the role of an unlikely hero—a quirky, time-obsessed slapstick comedian named Ziggy. When a mysterious artifact from the future accidentally shatters the fabric of time, Ziggy discovers that he can communicate with historical figures across time periods. To restore balance, players must navigate various timelines, solve riddles, and piece together clues from the likes of Cleopatra, Leonardo da Vinci, and Nikola Tesla, all while dealing with Ziggy's comically awkward attempts at making them laugh. Each choice influences the timeline, leading to multiple possible endings and hilarious misadventures.
