In 'Hello, Who?', players take on the role of a talentless stand-up comedian who wakes up in a quirky, noir-style city where everyone has mysteriously vanished overnight, leaving only their recordings behind. Armed with only their snarky wit and a crumbling notebook filled with terrible jokes, players must decipher the cryptic clues embedded in the recordings, engage with eccentric characters, and navigate through surreal situations to uncover the truth. Each decision influences the unfolding narrative, revealing dark secrets and comedic moments as the protagonist tries to piece together what happened and ultimately discover their own identity in a world devoid of laughter.
