During November 2024, Gao Rui developed the Enemy Attack Timer feature for the Combat System Minigame in the GameNova-Studio/path-to-the-throne repository. This feature introduced a time-based response window during enemy turns, requiring players to act before a timer bar UI expires; if not, the enemy attacks and the minigame ends. Gao Rui implemented the timer using GDScript and Godot Engine, integrating event-driven state management to connect UI elements with enemy logic. The work improved combat pacing and player feedback, enabling more precise tuning of difficulty. The solution demonstrated depth in UI development and clean architectural signaling between gameplay components.
