Games totally broken for me :/ First tutorial mission is unbeatable cause those damn pigs just stay at the back of the screen and throw long range attacks at my base :D
Maybe the game is unstable. If you refer my video I certainly open the game second time and resume my progress after that.
I'd suggest to clear data then open the game, and each time you complete a quest try to close and reopen the game to find out which point made you stuck.
