A fun concept, but it's really clear that it wasn't finished. I don't mind not having pictures, but I feel like you can make up for that by adding in a bunch of written descriptions. There's some descriptions, but they don't change often enough, and end too soon. Maybe add a couple cutscene-like scenes where she, like, bonks her head on a doorframe, or notices that a blanket she liked is now way too small? The only actual issue with this is that, at a certain height, the game stops displaying her height. It's really easy to make her huge, but, after a certain point, the only thing that changes is the text saying how many babies she's having.
Still, not bad at all.
