I beat it last night! I gotta say I was a little disappointed with the ending, especially how Ghirahim turned out. I thought he was the best Zelda villain I know, so it was kind of a waste. He's still awesome though.
I have to admit I cheated on the last Silent Realm, I downloaded a save right after it. I really couldn't be bothered to try it again and again. And they're the sole reason why I won't be playing this game again so soon, if ever.
