During October 2025, contributed to the GDCASU/VGDC-Game-2025-26 repository by developing a Denial Zone gameplay mechanic in Unity using C#. This feature introduced three configurable variants—Block Anything, Player Allowed, and Objects Allowed—implemented as prefabs with precise collider settings to manage player and object interactions within the game world. A dedicated visualization and test scene was created to streamline design validation and quality assurance, enabling rapid iteration. The prefab-based approach allowed designers to adjust interaction rules without modifying code, supporting a more flexible workflow. Work focused on 3D modeling, level design, and game development, with no major bugs addressed.
