In 'Chronochum: Whose Hello is it Anyway?', players take on the role of a snarky time-traveler who's accidentally become the universe's accidental ambassador of greetings. Every time they greet someone, the timelines shift based on the nature of the salutation. However, with a rogue greeting from a mischief-loving time sprite, things spiral hilariously out of control. Players must navigate various historical periods and futuristic societies, crafting the perfect greetings to mend broken timelines and avoid being forever lost in a 'Hello'-heavy chaos, all while encountering bizarre characters and outrageous situations.
