First I should warn you that the PC version does not have multiplayer but it is at least on Steam.
It's getting solid reviews but I would assume you would rather have opinions from people, so here are two pretty good sources:
Penny Arcade forums (started on about page 45 because that's about when people start getting the game)
Gaf impressions
Complete playthrough of the game (he hasn't posted the last two levels as of posting this yet)
Hope that helps!
-edit-
Also, this post is pretty epic. If you've beaten the game, you know what he's talking about. :-p
