Whatever. I've already posted shutting down warning on my page. Way to go pirates
It's a shame it came to this.
I know it's hard to have your hard work shared freely, but that's the nature of the internet, when you upload something people will share it, whether you like it or not (games, music, movies, porn... anything). You can make it harder by implementing DRM or something like that, but in the end the only way to fight piracy is to completely stop creating, which seems to be your intention.
Don't let your principles cloud your judgment, some things are out of your control so don't stress over it. You're making a good game and I'm sure you'll grow regardless of piracy, stopping now when you're just starting is not the best decision.
(The post on patreon says she'd rather stop the project than keep stressing over this)
