That was made back in february so hopefully we won't have to wait for long.
I was actually kinda surprised (I wouldn't say disappointed) how little porn the current version of the game had.
I'm guessing that there's going to be more but he simply hasn't added them to the game yet. If you look at his profile on Hiccears for example, he's got several image packs there (which he used to distribute on Patreon on a tier that's no longer available) featuring characters from the game like blacksmith x Hakken, blacksmith x Tholord and so on. All of these will probably be added to the game eventually. Here's hoping anyway!
Despite all that (and the engrish), the game is pretty great!
