In 'Chrono-Chums: Whose Hello Is It Anyway?', players navigate a zany timeline full of quirky characters from different historical eras, each with their own ridiculous viewpoints on friendship. You play as a hapless time-traveler who has accidentally forged bonds with these eccentric 'Chums' across time. The objective is to reconcile their conflicting ideas of friendship while using humor and time manipulation to resolve comical misunderstandings. Choose your words carefully and you might just mend a rift between a caveman and a Victorian poet, or even convince a space-faring robot that 'hello' doesn't mean a fistfight. Each interaction might result in wildly varying outcomes, ensuring that each playthrough is fresh and unpredictable.
