Developed the foundational mission system architecture for the Faster-Than-Scrap repository, focusing on scalable game state management and mission flow. Introduced core enums for both game states and mission types using GDScript, centralizing logic to improve maintainability and readability. Refactored the mission base script to eliminate per-frame processing, reducing runtime overhead and simplifying future feature integration. The work established a clear framework for adding new missions and transitions, supporting consistent enum-driven design. Demonstrated skills in enum definition, game development, and performance-oriented refactoring within the Godot Engine, laying the groundwork for future content expansion and streamlined mission system enhancements.
