8 screenshots?! I was hesitant to add the 3 I already did. Do I just just scroll down the page and screenshot the entire intro or something? It is all text.
As for adult content, it is interspersed through the entire game, ranging from mentions of anatomy in describing some beast aspects, and having the soft bits grazed in combat- or actual sex scenes on the other end of the spectrum.
All erotic scenes are technically optional (though you could not get the final ending without doing a few at least) and mostly dictated by Deception, one of the four stats. 6 people can be seduced total, 3 have 2 different scenes for disguised or regular approach, one is unlockable and has 13+ variations by choosing different combinations of transformations for her.
There is a guide to tracking them all down in the devlogs- Love&War.
