Nice app to demonstrate, what could be possible in the near future. It is a little bit too short to call it a full game. I know that it is optimized for the Iphone 5, but it would be nice to use it on Apples actual "flagship", the Iphone 6+. At the moment the two pictures are not positioned correctly on the screen, so that the app does not work with this phone. An update to fix that problem would be perfect. Afterwards feel free to program a larger full cardboard-game (or expand this one). I would for sure buy it!
