well preg is possible but not my main focus :3!
the little hero tho, I dunno much about preg games on itch or in general, and I'm not sure if it's against the ToS, so I couldn't give you an answer D:
Hmmm, I haven't seen many games about pregnant women, but I can say that most of them stop at pregnancy. However, I have an idea: create two or three artworks - the first one featuring a married hero and a Pokémon, the second one about pregnancy, and the third one with a child. Again, this is just a suggestion, but if it's possible, keep it in mind for the future. Alternatively, you can conduct a survey to determine whether others want to see such content. =)
