I am a big fan of the FB based version of this game so, when it came to iOS, I was thrilled and downloaded right away. The graphics and the game play are just as good as they are on FB. Fun, somewhat repetitive game play but the characters are great, the weapons are creative and the cows are awesome. From a cons perspective, in-app purchases are really the only way to enjoy the full extent of the game. Unfortunately, along with not connecting with FB when I try, I am unable to make any in-app purchases. When I click on the link, nothing happens. As a result, I remain in Chapter 5 with no way to increase performance or weapons. Can't even buy more energy. This needs to be addressed ASAP
