In 'Chrono Chums: Who's There?', you play as Max, a quirky time-traveling historian who has just discovered a portal in his cluttered attic. This portal connects him to various timelines, but there's a catch: each time he enters, he inadvertently alters history, creating unpredictable consequences in the present. Partner up with eccentric historical figures—like Cleopatra, Nikola Tesla, and a rebellious teenage Joan of Arc—to solve a mystery spanning multiple eras. Players must navigate conversations, make pivotal choices, and avoid causing 'temporal meltdowns' that could erase their existence. With humor woven throughout and mini-games that require quick thinking, players will engage in a race against time to repair the timeline before it's too late.
