Oliver Garcia Aguado developed a foundational Prototype Player Movement System for the Leyenda004/PMAP1 repository, focusing on early-stage gameplay mechanics in Unity. He implemented a dedicated Unity scene and a C# movement script that enabled four-directional player movement using WASD or arrow keys, with configurable speed to support rapid iteration. By isolating the movement system, Oliver facilitated early QA feedback and reduced risk for future gameplay milestones, laying groundwork for features like jumping and sprinting. His work leveraged C# scripting and Unity Engine best practices, providing a robust starting point for further development and ensuring alignment with the project roadmap.
