Enchanting universe
It is a beautiful entertaining game. Puzzles are sometimes hard, most of the times challenging, always easy to play.
It has great art and design, I mean really good, as for buying posters to hang on the wall, which I would never o even for my favourite movies. Great animations, music and sound effects.
It really immerses you into their misterious universe and makes you feel like you are really living in that world.
