Good game, please continue with the development; it has potential. Also, it would be good to explore the background of each character. As for the plot conflict, it could be that a rival coffee shop opens across the street, forcing them to compete by innovating their products. You could also add an event like a festival where different coffee shops or restaurants must showcase their cultural value to the city. You could also add mechanics to customize the cafĂ© or develop trust systems, beyond just romance, such as a team meter. Thatâs what comes to mind as a suggestion.
