Provocative Punishment adds a scene with Yui and Cain. To unlock normally, you need to go through the game with now sex then select the sex option with Cain at the end.
Futa Fantasy adds several scenes some currently unique to this game and some from the rookie. Basically it now contains all animations (in this style) with Remi in them up to this point. The game is linear so there is no branching path tips needed. I also redid all of the existing animations in the game to bring them up to a better quality.
I don't consider these games "Deluxe" versions but they were unfinished side projects (that have patreon versions) that I now consider finished. Moving forward I will just focus on the UMCH sequel and 3D ARIA game for the most part. I will more details on that really soon.
Of course art previews and gifs are posted, and I also managed to get a MMD video done with Zytra for those Enthusiast and Horny tiers.
