What people here always seem to forget, or just more of the same ill informed opinions arrive with new users, is that they dont charge you 10$ a month for their finished product. It is not a sales agreement. Its a support pledge for a running production, which is a completely different thing. You arent entitled to product support, or a refund, you cant hold them accountable for missing dates. You pledge on patreon to make this game development possible and they reward you with work in progress versions as they go. Thats all there is to it.
If everyone were like you, thinking not paying because the game isnt finished justifies pirating it here and on top of that talk shit and insult the devs then the game wouldnt even exist at all. So turn your brains on again and have a little gratitude that someone else out there is actually paying them so they can do this.
