That's a very interesting idea. Thank you for sharing I'll definitely consider it.I have a small suggestion for kaali and nixie.
I think they like strong men so it would make sense if every time you win a fight with them in the party
you increase their love. (weak enemy +1, strong enemy +2, boss +3).
I think it is better than spam kiss.
I hope my suggestion is valid.
I think you are doing a great job with this game.
Sorry for my english.
