Restore my purchase! – Pony Dress Up and Salon Games for Little Girls Review

I paid an outrageous $15 to unlock everything for my daughter. When switching to play on her iPad (mine and hers are linked for apps) it's telling me I have to pay again?!?! Please update the app with a restore my purchase option, this is insane. Not even worth $15 to begin with, never mind $30!
