During November 2024, Maria Guadalupe Fernandez Garcia contributed to the MatiasBiancoUsal/LightsUp repository by updating the level loading logic in Unity, ensuring that the LevelMenuButtons script now loads the correct 'Caverna 3.2' scene. She addressed asset management and scene integrity by correcting mesh references and refining scene configurations, which reduced the risk of scene corruption and improved build reproducibility. Her work involved focused C# development within the Unity Engine, emphasizing code hygiene and maintainability. These targeted changes enhanced the reliability of scene transitions and asset handling, reflecting a thoughtful approach to both feature delivery and bug resolution.
