During August 2025, Erwan contributed to the wiktorczernik/gmtk-2025 repository by enhancing audio playback testing capabilities for the game development project. He managed asset integration by adding two test audio files, test_light.mp3 and test_serious.mp3, directly into the Assets/Audio directory, following established project conventions. This asset-level approach, requiring no code changes, minimized risk and maintained production stability while improving QA readiness and reproducibility for audio features. Erwan’s work focused on asset management and game development workflows, leveraging his experience with Unity and audio pipeline organization to streamline quality assurance processes and reduce setup time for future testing scenarios.
