In 'Hello, Who Dis?', you play as Felix, an overworked customer service rep whose life takes a bizarre turn when he receives a series of mysterious phone calls from people claiming to be your past acquaintances, future selves, and outlandish characters. Each call presents a unique mini-adventure that requires you to solve quirky puzzles and make choices that impact Felix's hilariously chaotic journey to determine if these calls are a prank, a prophecy, or something much weirder. The twist? Your phone seems to have a mind of its own, leading you through absurd scenarios where you must juggle eccentric characters and their outrageous demands while uncovering the truth behind the calls.
