Loving this game so much! Would a relationship / sexual slider be something you'd be interested in? Like the more hearts you get with them the more dialogue / sexy time options you get
I've played games like that where you unlock things over time! Monster Mind is sort of that way too in a different way.
There are some conversations you can't have until you play the game a lot, and some sex options you can't unlock until you buy some rare items in the shop. I think as you talk to a Pokemon more and get the more personal conversations, you grow closer to them! I think they feel that way too.
