Not worth purchase, needs more levels

Downloaded this game for my daughter. Paid to get the extra levels...thinking it opened more than 2 levels...maybe another city or something. And was met with disappointment. It is ad ridden and hard to get around them. Last update the app did was in April 2015. Would like to see an upgrade or updated levels.
