First of all, love it.
You've made a great base for a rlly good game, I would love to see a lot more enemy types (monsters, and animals) and some features like, a big belly when alot of fluid is in her and parasitic pregnancy type stuff with birthing would be great imo. Also maybe some changes to her body.. like internal corruption.. bloated ovaries and womb and stages of pregnancy and visual change from usage etc.
Is that smth you intendto add?
