I agree, hopefully in future updates that will happen and I wish there was more to do with Mina like Heloise.I have been following this game for so long and am so excited to see the final product!
Just a question though, are you going to add options to the sex scenes to make them consensual? I always choose Heloise as my Dragon's mate and I kinda wanted the option to charm her and eventually have consensual sex. I like the idea of being able to give Heloise gifts, make her room more comfortable, and by treating Heloise well it could influence the naga child you have with her. Maybe even the option to give your child gifts or spend time with them as an influence on how they turn out.
I think differentiating Heloise from Valzira even further would be really nice. As well as differentiating how the Dragon treats his children from each elf consort.
For example, if pick the Tower as your lair and get the warlock through his experiments could make humans have children with your dragon blood to be more than kobolds.
