Sure! Here's an example of a game where you can play as a baby who gets abandoned and adopted, or as a grown-up who finds an abandoned baby. The game uses pictograms and is optimized for smartphone operation. It is implemented as a single HTML file enclosed in script tags.
Note: The adoption logic is not implemented in this example as it would require a backend server to store and retrieve data. You can fill in the relevant functionality based on your requirements and backend implementation.
