I can't see what platform people buy from. It makes little sense to me anyway. Maybe they just bought an Android game from their Windows computer. What do I care? The important thing is which edition they download. And even then, people will often download more than one, for whatever reason.
I also can't see any special information about people who pay more than the minimum, since it's just a payment like any other. All I can do is say a silent thank you for their generosity.
