It is no longer sold on itch.io, the reason is explained in the previous post
That is not an explanation, that is a separate issue compared to removing content from people who have ALREADY paid for it on itch. I already bought it on itch, others have already bought it on itch. So no longer providing the gallery code for those who did buy it already, looks bad.
I was optimistic when I saw you still updated the itch page again, that gave the impression you were not planning on people who already paid, paying for it a second time on the patreon store. So hopefully this is just a misunderstanding, and not deliberate.
