In 'ChronoChums: Hello, Who's There?', players assume the role of Ridley, a quirky time-traveling historian, who accidentally inherits a strange device that allows them to communicate with pivotal figures throughout history. One day, a mischievous time-traveler known only as 'The Echo' starts meddling with historical events, causing chaos across timelines. Players must navigate through different eras—ranging from ancient Rome to futuristic cities—by solving riddles, engaging in witty banter with historical icons, and making choices that will influence the future (or is it the past?). The goals are to collect 'ChronoChum' tokens to stabilize time and prevent reality from collapsing, while also dealing with hilarious and unexpected consequences of their actions.
