Worked on expanding in-game communication for TheDenSS14/TheDen by delivering an AAC Vocabulary Expansion feature. This involved adding new common phrases, species names, subject terms, and job titles to the AAC system, directly enhancing player interaction and communication within the game. The implementation was completed end-to-end using YAML for structured data management, with a focus on scalability to support future vocabulary updates. The work demonstrated skills in game development and localization, addressing the need for richer, more inclusive in-game dialogue. No bug fixes were recorded during this period, and the contribution laid a foundation for ongoing improvements to player experience.
