This made me want to write up a suggestion I've had lingering in the back of my mind for this game: a mode that turns her into a 'gentle' dom, with kinder phrasing and commands, and her not being that upset with you occasionally denying a command, especially harder ones. Maybe being okay with you cumming early, within reason (AKA not immediately.)
This could also bring about something like a "mommy" mode, because that's all the rage these days, and a "yandere" mode, where she'll be gentle until you piss her off enough, and then she's absolutely unrelenting.
Mostly unrelated to the other suggestions, but the only setting I could find that doesn't make her upset for cumming early, while also ending the session, is the sensitivity training. However, I'm not a huge fan of it because instead of being upset for cumming early, she sometimes gets upset at you for not cumming fast enough. I'd prefer a setting that goes like, "get as far as you can, but it's okay if you don't get all the way through the session." Correct me if I'm just missing a setting that does what I want, though.
I greatly enjoy this game already, but these suggestions would ramp it up to a perfect game to me. From what I've seen and read these suggestions seem possible in the engine, though how much effort they'd take is another thing. Then again I'm just a poor pirate and it's your game, Succudev, so do as you wish and prioritize what you want. I love your game regardless.
