I thought this was kinda stupid at first, but I found myself coming back to it over and over. And right now I'm fighting zombies in overalls, which is just awesome.
I'm seeing some glitches... in the store, when Jonathan 'confronts' Seth you can go back to the spot where he was sitting and the mouse will say he's there. Ditto when Rick first leaves. Still, it's a fun game, good animation, enjoyable story.
I think it's interesting that you can choose who's the bad guy (or girl), who is captured, who comes to the rescue, even have all three of them be evil. The only bad thing is that it runs out of different options very fast.
