Ever since your game was posted here and translated, your patrons have trippled from 10 to 30. Do you not think there could perhaps be some correlation there?
Regardless of the legality or ethics behind it, a much much wider audience is now exposed to your creation. If you're not in it for the money, then as an artist or creator wouldn't you prefer it being seen by a much wider community? If you do want the increased revenue, then the enormous amount of publicity having an English version brings is surely a good thing?
I understand you might be upset about your game being altered without your permission, however, whatever your reasoning behind creating your game, the outcome of an English translation is win-win.
Also, I'd strongly recommend removing the nudity from your Patreon page, Patreon have started clamping down on any public nudity and 'implied' nudity, and your page will get suspended if it's not removed.
