I honestly do not know if this game is either trying to tell a story about a brother being manipulated all his life by his sister, or if the both of them are just psychos, with the former having the brother do some actions that both lack empathy and logic to an extreme degree and with the latter also making no sense, since why would the brother really care much about anyone besides himself and his needs, which is clearly not the case. Truth is the game is a mix of both, maybe some other people can find meaning in this game but I've just been left disappointed.
