In 'Chronochums: Whose Hello Is It Anyway?', players take on the role of a time-traveling connoisseur of greetings living in a whimsical world where every era has its own unique salutation. After an unprecedented cosmic hiccup causes greetings to get mixed up across timelines, it's up to you and your trusty Chronochum—a bizarre, sarcastic companion that can shapeshift into various historical figures—to resolve greeting faux pas. Travel through vibrant settings such as a 1920s speakeasy, a medieval castle, and a futuristic utopia, and navigate back to their rightful owners' welcoming arms. Your choices affect the timelines and the reactions of characters you meet, leading to either hilarious misunderstandings or delightful reunions.
