In a word... EPIC
Oh man, this game is SO awesome! The challenges, the intense storyline, and at the end of level 9, OH MAN! I don't want to spoil it, but be prepared for even MORE epicness! Also, I dare ANYONE to attempt to do the 5 hour speed run, start to finish (I didn't make it thanks to the final boss kicking my butt! ARGH! SO CLOSE)
