Just finished my first playthrough of the game and I just wanted to say, it did not disappoint. Very entertaining from start to finish. Took me about five hours, got stuck on some parts. It kind of reminds me of "Little Big Planet", with point & click styled puzzles. Really enjoyed the stories of the characters, both amusing and interesting. Looking forward to playing with the rest of them.
So if you're thinking of buying this game, I'd say it's well worth the money =)
