Linfei developed the Chascar Combat Script Enhancement for the babalae/bettergi-scripts-list repository, focusing on terrain-aware combat logic to improve character survival rates during battles. Using JavaScript and leveraging expertise in combat mechanics and game scripting, Linfei engineered automation that adapts to complex terrains, enhancing both game balance and player experience. The feature was delivered as a single, well-documented commit with clear traceability to the related issue, reflecting disciplined code management. Although the work spanned one month and addressed a single feature, it demonstrated depth in technical problem-solving and a strong understanding of scripting for dynamic, terrain-driven combat scenarios.
