Great but some bugs. Short session time-occupier with a lot of modes, story, and events. Overall 4* game. -1 star for problems with 'watch a video/ad' for extra time, which requires closing the app if the Google play ad from the video loads in portrait mode; any treasures lost and spent resources wasted. Maybe 1 out of ten ads load this way, and the game gets caught in a loop opening google play.
