Over a two-month period, contributed frontend and UI/UX enhancements to the Bertie690/pokerogue and pagefaultgames/pokerogue-locales repositories, focusing on improving user navigation and gameplay flow. Developed a “Spend all” currency button in the gacha UI using TypeScript and JSON, streamlining the pull process for players. Addressed a gameplay issue by restricting EGG_LIST access during the SelectModifierPhase, preserving intended game mechanics. Enhanced the Run Info UI by implementing left-button back navigation, aligning with established navigation patterns and reducing user friction. Work emphasized localization, consistent user experience, and careful cross-repo coordination, delivering targeted improvements with minimal risk to existing workflows.
