In 'Chrono Chums: Who's There?', you assume the role of Felix, a quirky time-traveling librarian with the uncanny ability to speak to historical figures and fictional characters from various timelines. When your beloved library comes under threat from a nefarious bibliophile who aims to rewrite history, you must enlist the help of your 'chrono chums'—a cast of eccentric characters from different eras—to solve puzzles, uncover secrets, and navigate through a tangled web of past and future. Choices you make will determine not just the fate of the library, but the timelines themselves, and every character you enlist brings unique abilities and perspectives, offering multiple routes to victory. Will you juggle the chaos of history and save the day, or will the lines between past, present, and future blur beyond recognition?
