During October 2025, Alex Chen developed a foundational game state persistence system for the PurdueSIGGD/SIGGD-GAME-2025 repository, focusing on reliable save and load functionality. Leveraging C# and Unity, Alex introduced a SaveManager class that utilizes interface-driven design through ISaveModule interfaces, enabling modular and extensible handling of game state data. This approach established a robust framework for future save format support and facilitated easier testing and onboarding. Although no major bugs were addressed during this period, Alex’s work laid essential scaffolding for unit testing and future enhancements, demonstrating depth in incremental, commit-based development and a strong grasp of game development principles.
