In 'Chrono Chums: Whose Hello Is It Anyway?', you play as a disheveled time-traveling historian named Benny, who accidentally activates a malfunctioning time device while researching key moments in history through his wacky, sentient smartphone. Instead of exploring epic epochs, Benny gets stuck with his unpredictable time-traveling buddy, Charlie, who constantly interferes with timeline integrity. As you navigate through absurd historical mash-ups—from cavemen debating modern art to medieval knights forming a punk band—you must unravel the mystery of who triggered the time chaos to restore balance. Your decisions shape the hilarity and chaos of the encounters, and you'll need every ounce of wit to avoid utter historical calamity!
