In 'Chronochums: Whose Hello is It Anyway?', players take on the role of a quirky, time-traveling historian named Jinx, whose job is to preserve the timeline while keeping their wildly unpredictable friends—or 'Chronochums'—in check. Each Chronochum can alter time in bizarre and unpredictable ways with their 'Hello,' which ignites a time-looping paradox. Players must navigate chaotic historical events, solve comedic time puzzles, and manage the ever-changing antics of their companions as they work to uncover a hidden conspiracy that threatens the fabric of time itself. The game features branching narratives, humorous interactions, and quirky characters styled from various eras, ensuring no two playthroughs are the same.
