The game is actually pretty addictive, great time killer. But at one point it becomes tiresome, with all the grind you have to do in collecting resources, that's pretty much all there is to the game, "collect". The mechanics and the art style is good otherwise but I noticed few problems: Bad optimization, the game causes your device to heat up minutes after starting it. Frame drops thereafter. Way to many ads if you keep your data on. You either grind till death or watch ads to make your way.
