Difficult to transfer saved games by Storm8(How?)

I bought my wife a new iPad. We backed up the contents and transferred eveything to the new iPad. Eveything worked fine except the Storm8 or Teamlava games like Bakery Story etc. It turns out you can't just backup and restore those apps in a new iPad. Infact it's so difficult and confusing. There's instructions like emailing them the approximate install of the app. I can't even remember when I saw the app. If I can't answer them, they won't be able to help me. In fact the instruction says I need to get to a certain level first(that means if you may have to buy gems in game first) I call that a rip off. We already bought gems in game and now it's all useless.

For those of you or whoever was successful in transferring the saved games, can you share ti here? Don't bother posting a link to Storm8's site. Cause like I said it was useless for us.
