Fantastic. From a superficial manner a unique, engaging and epic journey with insane visuals, boss fights, soundtrack and so on. But if you want to go deep it has as many layers as you're willing to go, delving about relationship of the human and divine, morality, subversive hero's journey that makes you question your journey through the whole game. It's filled with symbolisms and inspired on hermeticism, biblical myths and so on to bring up an unique and interpretative story that will make you wonder about it for years and you'll always find new details or theories that makes you look at the game through a different lens, even years after beating it. Each can play the game and view it on a very different manner, has a harmonic ludonarrative that pushes it's themes and messages through it's mechanics, very meaningful ending... Masterpiece
