Developed a foundational game state persistence system for the PurdueSIGGD/SIGGD-GAME-2025 repository, focusing on reliable saving and loading of player progress across sessions. Leveraging C# and Unity, the work centered on designing a SaveManager class that utilizes interface-driven architecture through ISaveModule, enabling extensibility for future save formats and simplifying testing. The implementation established a robust scaffolding for incremental enhancements and unit testing, addressing the need for cross-session continuity and flexible onboarding of new persistence features. This approach laid the groundwork for maintainable game development workflows, emphasizing modularity and future-proofing within the context of Unity-based game projects.
