id maybe suggest replacing the signs with a study system
you could add a book and incy could add things to it for example using rough moves will inform him that a girl likes being roughed up or example
with miss primal a note might be this girl dislikes being mentally raped maybe i could convince her into fucking me if i acted weak
i think this game could do well with a study book over the signs as this could let you get defeated to study on how to make the girls do what you want them to do
another thing is to allow the player to talk with the girls before the fight you could add things like sex without combat based on if you earn it or not
