If you’re looking for ones that are complete and give ideas, the code for Overstuffed is very easy for a beginner to follow to learn RenPy with good comments: 🦃 Overstuffed - Weight Gain VN - release v1.0
But Overstuffed isn’t my best work, Housewife Simulator has more complexity and depth. It’s a romance, but not a dating sim: Housewife Simulator - FREE DEMO OUT!! ❤
My earlier games may be worth a look too, if you liked the others! Cowgirl Casino 2 and Cowgirl Casino
