Very misleading game. Starts off cute and like you are progressing but each time you reach a new city, it resets ALL of your money and you have to start over. You can only build new buildings in a new city so it defeats the purpose of playing. Wow, it sucked my time away. Uninstalling. Wasted my time and couldn't even get to the level to get paid.

after the first 3 levels the ads take at least 10 times before they go through. for some reason the ads don't go through as well. would give more stars if the bugs in the app wasn't so prominent.

the game keeps freezing. if you go to watch an ad to get more money it will freeze at times. then you have to restart the game. it gets frustrating.
