Yo. A interesting concept.
I like you art, your character and you story.
The game is really easy to learn and play.
I thing you need balancing . 3500 baby at day 160 it's a little bit. XD
Dont worry i dont forgot it's a concept. I think you can put a good scenario, some other guirl and other room with.
If you univers its really close about Furry, you can go to other way like egg or duplication.
Anyway all that to say that it's good work and it gives ideas.
Thank for you work, concept and time. Waiting your next move. ;3
