Worked on the crawl/crawl repository to enhance gameplay mechanics and reliability in a C++ game development environment. Delivered a targeted bug fix ensuring that spells designed to always hit remain unaffected by blindness, thereby improving combat predictability and aligning spell behavior with intended design. Introduced a Penance Title System that assigns a persistent title to players who abandon their deity while holding an invocations title, reinforcing thematic consequences and deepening player engagement. Demonstrated robust debugging and clear commit messaging, focusing on maintainable code changes. Leveraged C++ and feature implementation skills to improve both user experience and long-term gameplay depth.
