I just release my games for free on the Playstore. If I ever see a game of mine getting 100 000 downloads then I might reconsider.
Had to update my games to a newer API recently, and yes it is way more cumbersome than it was the first time I put my games up there. Don't know if I'll ever do that again.
All my APKs are also available on itch of course. Never tried other stores like Amazon and Huawei, maybe should check those out.
