I really like this game, the combat loop is pretty solid as well. But, I have some suggestions.
First and foremost, I think the Charm upgrade line is a little... a little too dry. I really like it, but I think it needs more "lustful" actions. I, personally, think it should have options exclusive for corrupted Characters, maybe with actions that force a "lewd event" to take place or actions that make more than one enemy to be charmed at once. Or even a passive that makes enemies with arousal above X to be charmed. Another suggestion is a new posture that makes the enemies gain more arousal.
Just like Charm, Zeal upgrade line too needs a little more work. Actions that upgrade the postures would be very good! Because two turns is too little, just a small buff in the quantity of turns would be perfect.
The others upgrade lines are pretty solid, me thinks, but I still didn't played focussing in punishment or in any other upgrade line.

Outside of combat, I think we should be able to do more actions in the morning, because essentially we have only two options: Purge or Rest, I think adding the option to preach in the morning would be great — or maybe the options to talk with our followers? Oh, I think a good options would be to let us walk among the people in a disguise, that could open cool interactions and lewd events that are completely out of the combat scenario.
Anyway, game is pretty good! Liked it a lot, it's clear that it have some rough edges but everything is going on the right direction, in my humble opinion. Best of luck to the developers! 😊
