Worked on the CleverRaven/Cataclysm-DDA repository to update tool crafting material dependencies, specifically requiring steel for crafting certain tools. This change was implemented by modifying landscaping.json, leveraging data management skills and a strong understanding of game development principles. The update aligned crafting costs with material availability, improving the in-game resource economy and enabling more predictable balancing for future iterations. The work demonstrated careful integration of data-driven changes into the existing crafting system, with clear traceability through version control. Utilized JSON for configuration and maintained a disciplined approach to repository management, focusing on gameplay balance and resource planning for players.
