I wrote one walkthrough :
Moko - Make 2 kids and the game will put pause on her until Naomi's story advance.
The reason I tied some events together is mostly because I don't have enough time to create both situations (pregnant and not pregnant). Imagine if Moko is pregnant with a visible belly, I would have to duplicate EVERY single image and animation and implement logic for each event.
Moko pregnant with no belly showing would be kinda odd
If this were my full-time job, I might consider it, but as a side job, it's just not feasible. I hope this sheds some light on why I occasionally suspend the pregnancy feature.
