That's how it is.
You don't like to have pay to play the new additional content, I don't like to have to set my game free to be indexed on Itch.
It will remain this way until paid games are allowed again, and it's starting to be frustrating to have to repeat myself 100 times on this matter.
Also recheck the definition of an AVN, this game isn't one.
Quests, Navigation system, Turn based Combat, Free roam, etc...
AVN are linear games with none of these features listed above, and they need a gallery to replay any scene.
