Miles O’Neal developed a heraldry customization feature for the SnowletTV/Invictus repository, focusing on expanding in-game coat-of-arms options for several fictional countries. He introduced new flag definitions with additional patterns, colors, and emblem textures, enhancing player personalization and supporting future content expansion. The work involved careful configuration management and game development skills, ensuring all changes were delivered in a clean, review-ready commit for traceability. Using text-based configuration, Miles aligned the feature with the project’s content roadmap, enabling richer cosmetic options and potential monetization. The depth of the implementation supports ongoing extensibility while maintaining a maintainable and organized codebase.
