Using only a retro smartphone loaded with bizarre apps and a plethora of cryptic voice messages left by anonymous contacts, players navigate through a stylized urban landscape. Every decision made affects the narrative path and uncovers layers of secrets about the vanished society. With each new character encountered, players must decode clues expressed in strange text conversations, strange memes, and elusive phone calls, ultimately leading to the shocking truth behind 'who said hello' and why silence reigns eternal.
