Congratulations on publishing your first app! It looks great, and a good variety of skins to choose from.
I really like the way you’ve integrated Tapjoy to allow unlocking of additional content. It’s a great way to make some revenue without forcing people to pay. And of course, there are still a few options to choose from for people who don’t want to use Tapjoy at all.
My only suggestion: maybe you could move the words “You have n stars” to be closer to the “Get more Stars” button? The way it’s laid out at the moment is a little confusing. I think it would be much clearer to have all the “star” related features in one place on the screen. Just an idea!
You make a good point about the placement of the “stars” items. I’m going to fiddle around and group them together - it does make more sense to do that.
