I understand the change in style, but I want to point out the fact that outside of the medium used (who will always be better than AI no matter what) the change in direction is maybe what a lot of people are taking wrong. The change in character physical features, colors and other things seems to be the main issue more than the change of style. Maybe something could be done about that with some update down the line. Maybe Koikatsu was just not the best idea even if relatively simple to use. No matter what you do stay strong on the no AI, but maybe staying in 2D would have been good to keep the identity.
