In the list specifying the rewards for investment on the Kickstarter page, the author specifies investors receive free copies of the iOS game. I was under the impression that Apple didn't allow developers to sell copies of games outside of the app store?
Each app has 50 promotional codes but I don't think they're supposed to be used in that way. It's also possible to 'gift' an app to another user using iTunes so the author would be able to use that mechanism to buy copies for the contributors.
It's 'free' so it's not selling. Developers are allowed to 'give away' copies of their apps with promo codes. Obviously this is super-gray area, but it's 'technically' not disallowed.
