Free Version Doesnt Work

I downloaded this app for my 5 year old daughter and couldnt figure out how to make anything work her. The in-app advertisements are relentless. The app froze up repeatedly. No way Id consider an in-app upgrade until I know the free version works. Id love to know how this app has 4 stars, I didnt see it.
