Very slowly. I'm playing/replaying a lot of the games to give better input on them, but my time is pretty limited.
While that game does/did technically use Koikatsu, its only for the posing. The devs redraws the models in 2D. I also remember seeing something in the discord about the dev switching to in house made blender models. I don't see it as a good fit for the list, but it is a really good game.
Thank you for the suggestion though.
