During March 2025, Brian developed a prototype audio-visual synchronization enhancement for the KGAMeta8PreCollaboration/NT repository, focusing on improving the realism and testability of the game prototype. He updated audio compression formats for sound files and systematically populated the YKD_Prototype scene with sequential audio clip names to facilitate precise audio notes placement. Leveraging Unity and his skills in audio integration and level design, Brian aligned prototype assets and notes layout to meet synchronization requirements. This work enabled more accurate user experience testing and demonstration scenarios, laying a solid foundation for future feature development while maintaining clear traceability through environment-tagged commits.
