Great game! I must comment that from all of the games I've played centered around spanking, this has to be one of the best by far.
Both characters and worldbuilding are well made and engaging, a lot of ecchi and pornographic games tend to forget both of these aspects. In particular the way in each the people in this world react to the whole spanking/healing from the healers of the Goddess feels grounded and very funny. This game is full of stuff you would see in a comedy anime of like Konosuba.
The whole medieval fantasy is my favourite kinda of cenario and this visual novel uses it in the best way.
I can also sense how much care you put into making sure that the punishment scenarios didn't felt too repetitive. There are only few but each one feels special and meaginfull for the story being told. My particular favourite is from chapter 2.
I really hope you are able to make more content like this, I am eagerly waiting for the second game with Olivia and her friends.
