Still new here.
What I mean by this question is, I have a game that is Name your Price. I have no idea if people paid for it or not, but I do know that I update whenever I make a new version. Suppose I upload a game and people pay $2 or so for it. The game is external so people download it from a site. Then I update it. Do they pay $2 each time? Or once they pay, is it free to download another version?
