I've just finished the game. I am not going to spoiler anything but I must say: wow at this game. the atmosphere, the music, the graphics...everything works and this is my favourite wii game since mario galaxy. It's even from third party. just wow.
I kinda felt sad at the ending. I guess there is going to be a sequel. at least I hope so. still the ending worked for me and I feleel the 20 hours I've put in this game was totally worth it :)
