In 'Chrono Chums: Whose Hello is it Anyway?', you embody a quirky group of time-traveling friends who stumble upon a bizarre artifact called the 'Hello-Gadget'. This device allows you to communicate with historical figures in their own time periods! However, there's a catch: every time you say 'hello' to someone, it alters their reality in unpredictable ways. As you navigate through hilarious misadventures from the Jurassic era to the Renaissance, you'll need to carefully choose how and when to greet each character to avoid creating chaotic alternate timelines. With branching dialogues, ridiculous scenarios, and clever puzzles, work together with your chums to set history straight without losing your sanity... or your friendships!
