Well, the game is not trying to be scary lol. I think zelda: the twilight princess is trying to be dark and it pulls that of nicely at times. This game reminds me a little bit of metroid prime 2. Nintendo was clearly in their dark world stage during those times lol.
I'm now at the very first mirror piece and I can't wait to see what happens next in the story. I know nothing about it except that Ganondorf will be in it, but I don't know how he'll be linked in the story XD
