In 'Chrono Chum: Whose Hello Is It Anyway?', you play as Timekeeper Tilly, an overworked, underappreciated guardian of the timeline who's tasked with repairing random time loops caused by careless time travelers. As Tilly, you will navigate through whimsical and absurd scenarios, from a medieval jamboree where knights are getting kicked out for wearing mismatched armor to a futuristic café where conversations have become a competitive sport. Your choices influence the timeline's silly and chaotic outcomes, leading you to restore order — or unleash perfect pandemonium. With a blend of humor and mind-bending choices, each path hilariously reshapes history while challenging your wit and creativity as you figure out, whose hello will you send back?
