Worked on enhancing gameplay balance and strategic party formation in the LandSandBoat/server repository by developing a selective mob linking and BCNM party matching system. Leveraged C++ programming and algorithm design to implement SUPERLINK-driven logic, centralizing and tightening mob linking rules. Addressed issues with cross-family linking in Einherjar and enforced stricter constraints for force-link mobs, ensuring only mobs with matching attributes could link together. Adopted a data-driven approach to improve maintainability and scalability of the linking logic, enabling easier future rule changes. The work focused on refining game development mechanics to deliver measurable improvements in both gameplay dynamics and code maintainability.
