Negative 1 star for app purchase, 2 for app usage.

If you uninstall then reinstall youve lost your $13.00 since the app does NOT unlock the parts that were paid for. Try to unlock again and its takes you to payment for $13.00. YOU HAVE TO CLICK setup, RESTORE to recover paid parts OR YOULL PAY MULTIPLE PAYMENTS should forget youve purchase previously. And Ive already double paid for unlocking parts.
