Developed and delivered the New Shuttle: Turncoat feature for the ARF-SS13/coyote-frontier repository, focusing on game development and level design. The work involved creating a complete map layout, defining shuttle entities, and specifying core properties such as name, description, price, and class using YAML for configuration management. To support shuttle operations, the implementation included UI button refinements and cargo bay extensions. All changes were consolidated into a single, descriptive commit to ensure traceability and facilitate potential rollbacks. The project demonstrated a methodical approach to feature delivery, emphasizing maintainability and clarity in both configuration and game environment design.
