According to the press release, the sequel “takes players on a journey back to Silence, the enchanting fantasy world made of dreams. Joining young Noah on a quest to find his little sister Renie, lost to him in the perilous real world, players will be taken on an emotional and spellbinding adventure to discover the mysteries surrounding the siblings and the breathtaking dreamscapes of Silence.”
Daedalic has said that several “familiar faces” will return in the sequel along with “a host of new features.” The developer didn’t mention any specifics, though the adventure game will likely adopt similar point-and-click mechanics as those used in the first game.
