The game is beautiful in all ways. The music is perfect for every scene, and every little sound makes the game all the more impactful on the experience. And could I would love to note that the intro is amazing in itself, the music on top of the beautiful and well done art, I haven't been that blown away by a game in years.
The controls are fun and easy to get used to, and the mechanics are also extremely fun. I love that to complete what would seem to be a simple task, you have to go through many different obstacles to get all different puzzles working. Going back and fourth through the map, allowing the player to get used to the controls fast, and get used to how the game works.
The story telling was nothing short of fantastic. The game tells the story slowly, and when there a vocals telling a story, it only plays after you've reached a certain point, which isn't the best idea, seeing as though if you get stuck for a while and finally get to the next point, a voice starts talking about stuff you probably forgot about. But I digress.
I love the game, and I rate it as follows:
Story telling: 9/10
Art work: 10/10
Music: 10/10
Puzzles: 10/10
All mechanics: 10/10
Teaching the player: 9/10
