Seems like a good start, a few thoughts:
1. Make the game playable with only a mouse for every action, including bringing up the menu and system options. You're making an adult game, people are going to be playing it with one hand and it's much easier for folks like me that use a mouse for everything (I'm also right-handed but fap southpaw, so maybe I'm a just a weirdo).
2. The dialogue decisions come up very quickly after clicking through dialogue, it would help if they had a half-second where they were visible but not clickable so the player knows they are there and doesn't click one by accident.
3. I'll point out that only allowing saving at set points instead of all the time doesn't work for a game like this, because you don't get anything if you die. If you allowed players to keep gained xp/gold through a game over in some way, it would make more sense (basically, how Dark Souls does it), but as it is it just adds tedium to have to redo filler fights because you didn't run back to a savepoint after every fight. However, if you want to keep it, it's up to you.
4. It would help if there were a turn timer on Iron Will, or if it expired at the beginning of your turn instead of the end. As it is, you basically have to figure out that it lasts 3 turns, and count turns to make sure it's always up.
5. I'll echo others that I'd like there to be a maledom route, but I'm not going to try and force my fetishes onto your game. If it's something you're considering you can count my vote, otherwise forget it.
With all that said, the art's really good (not just the body type, the general style looks good and Bunny is a cutie), the intro dialogue drags a little but is entertaining enough, and I'm eagerly awaiting the sex scene with the main angel.
