During October 2025, this developer expanded the TeamMyGummy/KUMI_TheNineTails repository by designing and integrating a new map, B1 기믹1, into the game’s tutorial sequence. Using Unity Engine and Unity Scene Description, they updated B1_Tutorial.unity and associated scene objects to introduce new gameplay mechanics, including lasers, laser machines, and spike traps. Their work focused on level design and scene composition, enhancing the onboarding experience and increasing content density for players. The developer’s contributions were delivered through two documented design commits, reflecting a methodical approach to feature delivery and collaborative version control, though no major bug fixes were addressed during this period.
