Developed core gameplay systems for the PurdueSIGGD/SIGGD-GAME-2025 repository, focusing on player and resource management as well as hunger dynamics. Leveraged C# scripting within Unity to merge player and resource management into a unified system, introducing a StatData class that enables refined movement parameters and robust player state handling. Implemented a hunger system that dynamically affects player stats through decay and health or damage interactions, updating related assets and scripts to support balanced gameplay. The work emphasized codebase consolidation and system integration, laying a foundation for data-driven tuning and future extensibility while prioritizing maintainability and reducing integration risk.
