Noooooooooooo!! I'm playing this game on my Smartphone right now.. spoilers spoilers spoilers.. still... good memories tho 
Ah, now I know the story too! But its probably even more fun to watch if you had played it ;)

The best part about this game is the art.
And the music.
And the jokes.
And everything else.
