During March 2025, Presr delivered a complete stairs feature for the Mysterion83/Collaborative-Game-Development-MCM431 repository, focusing on interactive level design in Unity. They implemented animation controllers and an interactable switch, enabling dynamic up and down stair animations controlled by user input. Their approach included updating test scenes for rapid validation and refactoring library scripts to support the new functionality, emphasizing reusable components and standardized animation workflows. Working primarily with C# and YAML, Presr’s contributions improved prototyping speed and cross-scene reusability. While no major bugs were addressed, the work demonstrated depth in animation, scripting, and collaborative game development practices.
