I love this game. Some of the puzzles are very difficult but it is fun figuring out how to solve them. You can almost feel yourself getting smarter as you play. The only thing that teaches you how to play is the puzzles themselves. Figuring out the puzzles is like learning a new language. The world is beautiful to look at and you can find yourself just staring at the environment. This can then lead to finding secrets. Everything in this game is placed meticulously. Just play this game.
