I have a first generation I pad running 5.1.1 Looking at this game specs I should be able to play it. So far I cant even open the app. I just want to play and enjoy a great game. I have taken many steps to try and fix the problem such as uninstalling the game and reinstalling it. Restarting the I pad. Etc... I dont know how to send a message to the developers but I will try. I will change this rating if I can fix the issue and I can try the game. Until then I guess Im out the price of the app with nothing to show for it.... .... This looks like a great game.
