This Adult version here, is more the interpretation of our animator/creator Mayorto. The one on Steam is more of the developers' construction, where Mayorto was mostly the animator.

Here we can see a good homage to KooooN Soft, with titles like Shinobi Girl, Angel Girl, Witch Girl and Kung Fu Girl. I definitely like the formula, and I miss it in the more recent erotic games, so Mayorto's work is definitely appreciated.
(The dogs have to be there. Everyone complaining about them either hasn't played any KooooN Soft title or orders his Martini without the olive)
