Well... Some thoughts about "piracy" of this game and authors idea of "if some people will have this game for free ill stop to make it further" (if say shortly).
1) Piracy as a case helps to make game famous. Your old free builds didnt make me pay any attension. If people look for your old work and dont want to share in some circles you will stuck.There to many examples, when authors give people latest versions in a week after patreons (necropanzer, starvy). Some of them are moderators on their game topic, and such open cases does not making damage for support (boko877, excessm).
2) People who can pay - will pay to help, people who cant (dont want to pay) wold not do this even game is not available. Cose there is many free awsome stuff and they can wait... once a year recall your project... and you will be boiling with your subs and cant get new.And suporters oftenly suporting not for an absolutely exclusive content only for them, but for ability to vote, to have early access, even for some teasers or custom orders.
3) new versions making new comments on forums and showing the best of you can do. So game higher on forums, more people looking and thinking about suporting or sharing game into publicity. Some time further some of them become fans and ready to pay not only attension.
So... you can close up any leaks... you can show builds without animated scenes and promise that in latest build all is 100% better... you can say that everyone who downloaded game could support you on patreon but didnt because game available for free (no, pirates usually simply passing by)... you can do everything you count wise... BUT there some better ways that can show you and your game to the world.
(Your loyal PIRATE)
