Yo.
I'm not very good with English, so I'm not good at giving you real feedback on your game, sorry.
It's a shame there aren't any images, otherwise I think I understood most of it. However, I can't give an opinion on your writing level.
I like the story. The hero's reaction is a bit cliché. The setup is too, but the story works well. I stopped counting from 400 children with pregnancies to over 80 children per birth. The upgrade system works. More text differentiating between belly levels would have been interesting. I wouldn't have said no to more descriptive scenes about the pregnancy or childbirth phases.
Anyway, I practiced my English (lol) and I still enjoyed the story, even though I would have liked to reach the end. But since it was starting to go around in circles, I figured there weren't any.
Thanks for your project. I had a great time. I'll keep an eye on how it progresses. See you next time, and well done. ^^
