Anyway, I just played through the ending again yesterday, and when the credits first start, something caught my eye.
The first scene is of the mountain from the bottom of the snowy slope right beneath it, where when you get to that point there's the thunder and it's a blizzard and stuff and you're really struggling.
Well, the grave directly in front of the screen is glowing. It's glowing, then the glow goes out, and then right after that a 'star' suddenly comes from the center of the mountain, and then it travels through the credits to the beginning again.
So, one reason I love this game is because you can interpret it how you like, or what you feel it is about.
I feel it might be something like this: All those graves are not from the cloaks who failed the journey, but from those who died in the war. And when a cloak makes it to the mountain, it sort of lets him achieve a form of enlightenment, and 'unlocks' another grave, where that cloak will be reborn from the mountain and allowed to make the journey as well? Such as a sort of system to where only a few cloaks at a time can journey, and if they make it, they release another soul to partake in the journey? But if they get lost, they will have to wait to be reborn to try again.
I'd love to hear other theories on aspects of this game.
I want to do this someday though, so many people say how wonderful of an experience it is.
