itch.io is no longer allowing adult games to be sold through them. Other developers selling their games on itch.io are selling direct which means all their transactions go directly through PayPal. PayPal does not allow the sale of adult material, so many of those people are having their PayPal accounts shut down.
This is not a decision I have made. This is a decision itch.io has made. As I said in the note on the main page of A Petal Among Thorns, if you contact me through Discord I can get you a copy.
