Caleb Schin Yee developed and integrated a suite of test-level assets for the Humber-Game-Production/GAME259_2025_Winter_A repository, focusing on improving level design workflows and testing infrastructure. Using Unreal Engine and leveraging .uasset files, Caleb created targets and jumpable platforms to support iterative level testing and player navigation validation. He enabled the ElectronicNodes plugin within project settings to enhance the testing of player interactions and streamline the QA process. While the work was limited to a single feature over one month, it demonstrated a methodical approach to strengthening the foundation for future game development and level design improvements within the project.
