Chaos;Child is a visual novel, which is split into multiple different story routes. During a first playthrough of the game, the player can only play the main narrative; after finishing the game once, other routes that branch off the main narrative at different points become available. Each route focuses on one of the game’s characters, dealing with character motivations and secrets not revealed in the main narrative. At multiple points, the player gets the option to choose whether the player character should experience a positive delusion or a negative one; they can also choose neither option. These choices change the player character’s world view, as well as who he trusts, and are what causes the story to branch into different endings
