In 'Chrono Chums: Who's There?', you play as a quirky historian who accidentally activates a mysterious time-traveling artifact while cataloging an old library. Each time you use the artifact, you are whisked away to different pivotal moments in history, where you must solve riddles, navigate political intrigue, and interact with famous historical figures—all while trying to figure out who (or what) is scrambling the timelines, leading to hilariously chaotic outcomes. Can you restore the timeline before you become a historical footnote yourself?
