1. I believe that "Feed" allows you to see the activity of accounts you follow, including when they update a game. You do not need to delete the old version of the game on mobile, the APK will automatically update the old one. I acknowledge that some of the blame for the weird updates lies with me and my bewilderingly cuckoo development cycle (i hit build and upload after every minor bugfix and then i do it again when I find another bug)
2. I have never added anything to the game that I do not personally enjoy, and I have no problem saying "no" to requests that I don't want to do. I am grateful for your concern, but like you said, I am the captain of my ship.

4. Steam seems like the ideal platform for a paid game, but this is a free game. If I make a paid game in the future, i'll make it available on both Steam and itch.io
