    This was a nice, simple and fast math test. With this latest update, it doesn't even play. I see a blank screen with a background and only option at bottom don't do anything. Profile, Link player, and About. Not sure the changes to the UI were successful. UPDATE: March 2015... App is fixed!! Now launches and I can play. Would like dark screen option.
