During August 2025, List focused on expanding cross-platform capabilities for the Cosmic-Shore repository by delivering Linux build support. They introduced a dedicated Linux build profile and a scripting define, leveraging C# and YAML within Unity to enable conditional compilation. This approach excluded non-Linux gameplay scripts, such as the Dialogue System, from Linux builds, ensuring a clean runtime environment. List validated the end-to-end Linux build pipeline, producing runnable builds that reduce platform friction and broaden the game’s audience. The work demonstrated depth in build engineering and cross-platform development, addressing deployment challenges and enhancing engineering efficiency for future development cycles.
