Ico

Ico is a game about a cursed boy (also named Ico) sent to a castle to be left for dead.

He escapes his tomb and wanders around until he meets a girl in a cage named Yorda. She speaks in a language Ico can't understand and needs his help to get around.

Ico protects Yorda from shadow creatures sent by the queen to recapture Yorda as they both try to escape their prison.
