This is an astonishing great game, a puzzle game that made me feel smarter the more I played it, a truly satisfying experience. The only reason this is not 5 stars from me is the absurd permissions the installer wants on OSX - receive keystrokes from all applications? Is this infested with some kind of key-logging malware? Luckily apple has a granular permissions model, you can tell The Witness to restrict its witnessing to it's own business.
