Good games... But waste of money

I had downloaded this game when it first came out. It needed a book to unlock the special planes- I finally found the book but it never did unlock the planes.
Finally after a year they allow people to buy the planes straight through the app.
Luckily my son loves books but the book scanning function never worked.
