I love playing this game. It would be 5 stars if the game worked event bough the the graphics are pictures and not true scale. I give it 1 star because the game is broke, I bought the full version and paid the $2.99 for a bunch of the upgraded fields and planes. Unfortunately the purchases will make the game crash every time you open it, it crashes. I un installed and reinstalled. The game came back and it worked I hit the restore all purchases button. It starts crashing again. I got ripped off. Heres a tip to the developer, dont sell your upgrades for $2.99 a piece if your software cant handle them. It makes it look like you are intentionally taking money on a faulty product.
