Worked on expanding and refining game levels within the BlackCatMax/LD04 repository, focusing on map development and asset integration using Unreal Engine. Delivered two new features by introducing the L_Alexey.umap map and updating existing maps such as L_BaseLevel.umap and L_Polina.umap, with careful attention to stability through selective reverts. Enhanced gameplay immersion by integrating new warehouse assets and environmental elements, emphasizing modular level design and improved player experience. All changes were managed through targeted, traceable commits, demonstrating a methodical approach to version control. The work showcased skills in game development and level design, with a focus on content quality and maintainability.
