Great concept w/ the cards etc. This could've been a very popular game. However, the scaling and cash grab is disgusting. Play is limited to about an hour before it becomes apparent. You'd likely make more money if you balanced it better. I'd give it zero stars if I could.
The bug where the screen goes dark after changing around inventory makes the game unplayable.
It looks like it could be a real hit but that bug desperately needs to be fixed.
