In a sea of teasers that end before they even begin, this demo serves as a complete story, which is already unique enough.
I went in blind and do not regret it, the simple "you cannot save him" in the description of the game destroyed me all over again as I rushed to leave this review once I saw the credits roll.
What an elegantly and beautifully told story. Also, credit to Asrielle, who's art already had me sobbing even before the text would deliver the extra punch.
