In 'Chrono Chums: Who's There?', you play as a quirky, time-obsessed detective in an alternate 2023 where time travel is a common but strictly regulated activity. Your best friends, who have punctured the veil of time for a joyride, accidentally unleash a temporal anomaly that begins to unravel historical timelines. As you jump through various eras — from the Roaring Twenties to a dystopian future ruled by sentient coffee machines — you'll need to gather clues, negotiate with historical figures for assistance, and solve puzzles that change based on the time period. With an engaging narrative, humor, and character development, the game explores themes of friendship, responsibility, and the importance of historical events. Can you fix the timeline before the past catches up with you?
