During December 2024, work on the gmuGADIG/FetchQuest repository focused on expanding narrative-driven gameplay by implementing a conditional dialogue system for the Princess character and integrating a new Shopkeeper NPC. Using GDScript, the developer designed data-driven dialogue scripting and state-machine based quest progression, enabling branching paths, quest flags, and dynamic guidance for players. Engine and configuration integration ensured reliable NPC interactions and scalable quest design, while stability improvements addressed quest state management and dialogue branching. This approach established robust patterns for future content expansion, emphasizing narrative design, NPC integration, and disciplined version control to support maintainable and engaging game development.
