Md. Anbu developed the Wizzy Quest Expansion for the endlessm/threadbare repository, delivering a new narrative-driven feature that introduced storyline elements, characters, visual assets, and a sequence puzzle to enhance player engagement. Working primarily with GDScript and the Godot engine, Anbu focused on integrating 2D animation and sprite management into the core game loop, enabling scalable future expansions. The implementation included scripting gameplay logic and asset integration across initial scenarios, supporting richer onboarding and retention through puzzle-based progression. The work demonstrated depth in both design and engineering, covering end-to-end delivery from concept through code and visual asset integration.
