In 'Hello, Who?', you play as a quirky detective in a bizarre, surreal city where every resident has forgotten their own identity. The catch? You can't leave until you help them remember who they are by deciphering their fragmented memories through intricate dialogues and absurd puzzles. As you mingle with eccentric characters—from the amnesiac cat-groomer who once ruled a feline mafia to the talking lamppost philosophizing about the meaning of shadows—you'll uncover dark secrets that threaten the fabric of reality itself. Will you piece together the enigma of this city, or will your own identity be lost in the process?
