Guess POTUS

For the midterm, I updated one of my previous apps. The user may choose one of five time periods. The first four time periods contain about eleven presidents. A correct answer is 30 points. An incorrect answer is 15 points. The level increases every 300 points. The correct answer will always contain a spin animation. If the user clicks the grey button, a list of the presidents for review is presented.
