Will you be able to customise what Anna wears ? If yes, Will be there more revealing putfits for Anna’s slut route?
Only in the way you can select outfits within the studio today and the random costumes she wears in events. Having a costume selection option would require a major rework to the sprites and CGs as the images and sprites are static images. e.g. 40 images become 400 with 10 sections.
On slut, there was supposed to be final evolution costume for Anna like the kitchen outfit, with a different one for slut/love routes. However this seems to be have been dropped and not mentioned since 😔 You can see glimpse of what this would have looked like by taking picture of Anna in the Club for slut route.
