Worked on enhancing the Unciv repository by addressing a reliability issue in unit selection within city views. Focused on improving user interaction, the developer introduced an allowPropagationProperty to manage event propagation, which reduced mis-selections and minimized regression risk. The solution was implemented in Kotlin and involved targeted code cleanup and refactoring, removing unused imports and redundant logic to improve maintainability. This work not only streamlined the interaction layer but also lowered technical debt and future maintenance burden. The changes resulted in a smoother user experience and improved traceability, leveraging skills in Kotlin, UI design, and game development.
