Cheers, for the reply. It is definitely top of my most wanted list. I guess I will have to use the older 'Lite' and separate 'Premium' model on the app store.
As an interesting experiment I will be also be building another build in Stencyl (mainly as a remix version of the game for Flash). I will report back on my findings as I go along (only in a constructive manner of course but I may have some good suggestions for future builds working this way :).
