MGWU co-founder here, to clarify we take 20c of 99c (30% of the 70c post Apple) so the developer keeps majority :). The localization on iTunes showed up by accident due to the Appirater library (https://github.com/arashpayan/appirater) being localized, will be fixed in an update
We'll definitely explain this in a clearer way as we move out of beta. Out of 99c Apple takes 29c and we take 20c leaving the developer with 50c, so slightly over half :)
The game looks fantastic, and I'd just like to say: I love the idea of MGWU. Coming out of an iOS game development course (aware that you don't offer traditional "courses", but still) with a polished iOS app seems like a great deal - even better when your profit is tied to the success of the apps themselves. Love it.
