There's a lot of potential here if the dev makes some major changes/improvements. Some QoL suggestions:
- Body parts are too granular. It's...interesting to be yelled at for staring at somebody's eyebrows. I think a serious simplification on that front would be good.
- The current touching system, as everyone has said, is insanely difficult and ungainly. The whole system isn't really for me personally (particularly the groping/unwanted touching stuff), but what I'd do is implement a point-and-click system. Click a body part to touch, then maybe use the mouse wheel to adjust strength/direction. You should get yelled at for being too strong because you chose to be too strong, not because it's nearly impossible to control how strong you are.
And highly subjectively, I would love to have a full dialogue system, since the 'story' is what I personally like about this idea. You should be able to judge a model's personality based on how she reacts to dialogue choices, not...however you currently do it. And you should be able to convince them to do things in a natural, logical way rather than just touching random body parts and hoping they work. I know it'd be complicated, but given that there's already a status bar system in place, the worst part would probably just be the amount of dialogue writing you'd need to do. (Hint hint, I'd love to help.)
