Some hopefully constrictive criticism:
The only sounds during the H scenes are that goofy pounding sound, which I guess works as part of the aesthetic. But, some more realistic moans from the protag would go a long way towards auditory eroticism. And since this is in 3D, you might as well give the player camera control, or at least give them a few different camera angle choices, along with some zoom control.
It's really hard to get rid of a curse. I went through an entire playthrough and couldn't find a uncurse scroll or anything like that. In fact, I've not found anything that got rid of curses in many different playthroughs. Perhaps some sort of altar like device that got rid of curses could be added.
I also think fucking doesn't do enough to the enemy. It lasts maybe 5 turns, and they are back to fighting you again. And it's not like a stun where you get free hits, either. I think it should charm for 5-10 turns, so that there's some strategy to doing it in a room with multiple enemies. Perhaps they would ignore you for longer, too, so that you have a chance to run away without a chase.
I noticed that stripping lasts one turn, at least for minotaurs, which isn't useful at all. If the clothing has some sort of AC effect, it should be more of a risk/reward here. Have a chance to get away from an enemy, but permanently downgrade your AC. One turn ain't enough.
