In May 2025, Andrew Michael contributed to the GDACollab/Well-Witches repository by delivering a comprehensive boss combat balance pass using Unity and C#. He introduced a new attack-indicator material and tuned core combat parameters to enhance play fairness and visual clarity. Andrew increased boss health, refined shield damage scaling, and updated lunge logic to ensure each player is hit only once, addressing issues of accidental or unfair hits. He also recalibrated projectile damages and added rain effect parameters, establishing a solid foundation for future balance iterations. His work demonstrated depth in combat balancing and effective use of Unity Engine features.
