Do not go on Amazon

The game can be via the Amazon website refer, but does not end up in the App Store application. After I downloaded it directly from Big Fish, I could play for a while, until the required fee-based activation. And since I would need just a credit card, Checkout by Amazon will not do.
I do not understand why Amazon offers the game so still on the website. I had spoken to the support, but that is not rigged.
Too bad, because the game itself like it stylistically very good, and I enjoyed even until the end of the "demo / intro mode". But supposedly offer for "Collector's Edition" for free, but then did not make the download, and then require mid-game money, so it can be played to the end, of a star is almost too much.
Conclusion: Big Fish Games bought certainly a nice game, but with Amazon a sham that should not be available here
