During December 2024, Antoine developed the LVL_4_Depression level for the Boooork/AfterLight repository, focusing on core level design and gameplay flow. Using Unreal Engine and UnrealScript, Antoine created the foundational blockout, integrated visual assets, and iteratively refined room progression through 16 commits. The work included implementing and adjusting triggers and puzzles to support smooth player navigation, as well as resolving soft-lock issues that previously hindered progression. By stabilizing the LVL_4_Depression.umap and ensuring a testable, playable path, Antoine provided a solid base for quality assurance and future iteration, demonstrating depth in game development and level design within a short timeframe.
