In 'Chrono Chums: Who's There?', you play as Max and Ruby, quirky time-traveling siblings who accidentally disrupt crucial points in history thanks to an experimental time portal built from a toaster and a blender. As they hop through different eras—like the caveman age, the Renaissance, and even their own awkward school days—players must interact with historically significant figures (and some unexpected cameos) to set things right. Each era presents unique challenges, riddles, and zany characters that need your comedic approach to problem-solving. Your choices shape the outcome of history itself, and who knows? You might end up creating new legends along the way!
