Did previously give 4 stars because of the game crashing every minute now its crashes every 20 seconds of game play and i have to keep reloading. I dont mind watching the adds because it gives you resources you need, but the constant game crash and reloading is beyond ridiculous.. i think the pop up adds at the bottom of the game are interfering with the game, or either you have a hacker who is jealous and wants to ruin your good idea.. for now have uninstalled untill things are improved
