Playing The Unfinished Swan feels a lot like being three years old. You make a terrible mess, and then when someone asks you "Why did you do that?" the only real answer you have is that, weirdly, it felt right. There was just something about that wall that begged to be drawn on with crayons, something about the VCR that just begged to have a PB&J sandwich in it.
It's an urge, not a reason. And The Unfinished Swan captures that magnificently.
Stephen mentioned in his review that he was a fan of the texture of the sound in the game. I like the visual texture. There's something childishly satisfying about throwing paint hard against a wall and seeing it splatter in every direction. There's something amazing about watching water evaporate into nothingness. There's nothing rational about it: That's just how it is.
