Doncuentacuentos contributed to the Cataclysm-BN repository by developing gameplay features and refining balance systems using C++ and game development best practices. Over two months, Doncuentacuentos enhanced stealth mechanics by adjusting crouch-based visibility, normalized seed weights to support consistent balance tuning, and resolved a turret interaction to ensure correct skill application. Additionally, Doncuentacuentos improved user onboarding by integrating in-game UI guidance that clarifies wind turbine and mill power output, reducing ambiguity for players. The work demonstrated a methodical approach to both feature delivery and bug resolution, with careful attention to gameplay fidelity, user experience, and maintainable code integration.
