Thank you for your analysis of this situation. I consulted a friend who programs video games for a studio that makes Android games (Viva Games Studios), and he told me bluntly that if I don’t pay for advertising, it’s very difficult for my games to be downloaded. That’s how this studio does it. He worked on this game (https://play.google.com/store/apps/details?id=com.Naolito.SaveTheCat), and on the first day it was released it reached 500 downloads, in a week it already had 8,000 downloads, and now it’s at 50,000.
