Christer Tysse developed foundational prototyping assets for the LunarLander2025 repository, focusing on accelerating early-stage iteration and testing. He created a dedicated Unity test scene, TysseTest.unity, and updated build settings to streamline isolated gameplay validation. Using Unity Engine and OBJ file formats, he introduced a Landing Pad 3D model with detailed vertex and texture data to support rapid mechanic prototyping and level design. His work emphasized scene management and asset pipeline clarity, enabling faster exploration of gameplay ideas. While the scope was limited to two features over one month, the contributions established a robust groundwork for future development cycles.
