Who's Lilia? [F2U CODE]

Who's Lila? is a video game developed by Russian independent game studio Garage Heathen, released in February 2022. Described as a "reverse-detective adventure", the game is an adventure game notable for using the manipulation of facial expressions as the means that the player uses to communicate with characters in the game.

Who's Lila? is played from the perspective of the protagonist, William, a teenager who finds it "difficult to express emotions" and has to make "a conscious decision each time [he] moves a muscle". The game features a nonlinear narrative surrounding the disappearance of classmate Tanya Kennedy, as William must act naturally in the face of suspicion from classmates and authorities as the last person who saw her alive. The player is required to make branching choices through multiple playthroughs to discover multiple endings that provide greater insight into several emerging mysteries in the game, including the circumstances of Tanya's disappearance, the deeper aspects of William's psyche, and the identity of the titular Lila.
