Sloppy on the edges

I have every Duck Duck Moose game. The relative quality of their apps is very high given the rest of the stuff in the app store. But, there are tiny things with each title. This one isnt consistent in terms of age appropriateness across the whole app. My son is so bored by the first couple activities, I cant get him to play anything else in the app. Their Math app has the opposite problem.
