What truly makes The Witness everything that it is lies somewhere between the fundamentals of the puzzles and the deeply philosophical of everything else. These two work in tandem, complementing each other even when they seem worlds apart. There are so many layers of separation between the two that it's almost impossible to perceive or even conceive. But, they're there, working hand-in-hand and, on some level, one in the same. You'd be hard-pressed to declare that one of these components is closer to defining The Witness than the other.
Truthfully, I wish I didn't have to score The Witness. I don't want to set people up for that expectation; I don't want a voice in the back of their head that says "Okay, when does this become a ten?" In a way, that's unfair and detrimental to how the game should be experienced, which is as open-minded and unassuming as possible. Don't go to The Witness. Let The Witness come to you.
