This is a great app with one flaw: the upgrades are too expensive

Seriously! I would guess that you would sell many many more if they weren’t so pricy. It isn’t as if this is really nescesary , it is just for fun. So why would i want to pay so much for add-ons? Otherwise , it is truly well done. Bravo!
