Struggling to put into words how spectacular this game is.
Play it.
You will laugh, you will cry, your jaw will drop, your heart will break.
The game alone is brilliant, but the visuals, sound/music & story have no place being this good. It truly is a work of art.
To quote a character in the game itself:
"... art can be a Window and art can be a Mirror. And great art. Great art is both."
This game is "Great art," and you will feel/experience this as you play the game.
Just make sure to spend enough time talking to people in Lumiere during the prologue/intro. You'll thank me later.
