Long term playing unless you are willing to spend real money. Update 5/27/2019: it takes a while to be able to get the ruby keys you need to advance in the game, that's what I meant by "long term playing", unless you buy them of course. But it's still possible. I'm adding a star because I do enjoy it after all. One improvement is that some constructions, like a water fountain ⛲, could be allowed to be built away from a road, so it could be in the middle of a 9 squares garden. Need highways too.

Fun game but after an amount of progress that varies by device performance the game will begin freezing a short time after you open it. Im very disappointed to be unable to continue after making so much progress on my city and angry at the developers for designing a game to stop working after you play it too much. Also the ads are very intrusive. You will be constantly interrupted by videos you are made to watch. It's always appalling to be ambushed by an unexpected advertisement while you're actively doing something else. I close the game every. single. time. You aren't getting hits on those anyway try designing something user friendly for your ad system devs!
