Your upcoming priorities sound very intriguing. Are you leaning on the player being able to control how they behave after defeat, or leave that up to randomization? I think allowing the player to control that punishment or submissive behavior after a defeat sounds fun.
Sounds great either way you decide to go, but I'm especially happy to hear about you working on the emotions of the fight. I think that's an area that's really untapped, like seeing a character that's controlling the situation just smirking at her frustrated/angry/crying opponent under her would be awesome. I think it's very worthwhile to add that extra detail.
Regarding animations and clipping issues, I understand that can be tricky with as much physical diversity as you allow your characters to have. This is obviously just my opinion, but a lot of leeway is deserved with the amount of options available. I guess I'd just say don't let pursuit of perfection impede progress with regard to most, if not all, artistic endeavors and ignore the ignorant folks that complain that things aren't perfect.
That being said, I have a few more attacks that may or may not be easier to get around clipping issues. Those would be a chest/breast claw/rake maybe taking a side approach to avoid most of the size issues and also a humiliating nipple tug or pinch that would maybe not be so easy to hide, but would be fun to see.
I'm excited to see what new clothing options and hairstyles you come up with. I've read you self-criticize rather harshly about your game's graphics somewhere, but for what it's worth, I liked them just fine before the improvements and think they've only gotten better with the new update. Customizability and creativity often outweigh pristine graphics in my book, but I mean I'm an old school, pixel game appreciator and am only one person, so take that for what it's worth.
Regardless, hope you continue to have fun making the game, it's been a joy playing it.
