In 'Chrono Chums: Who's There?', players take on the role of a quirky time-traveling historian named Tilly, who accidentally turns her ancient relics into sentient companions dubbed 'chrono-chums.' Venturing through iconic moments in history, Tilly must solve time-bending puzzles while ensuring her chums don't accidentally rewrite history with their often absurd antics. From aiding Cleopatra in her wardrobe choices to navigating the chaotic streets of Victorian London with a bumbling steampunk inventor, players will experience laugh-out-loud moments while unraveling a plot orchestrated by a mischievous time-traveling villain determined to erase their history. Each choice counts, leading to multiple endings based on the player's interactions and decisions with both the chums and historical figures.
