What problem does it solve? Game interfaces in Three.js projects often end up as generic dashboard-style stat cards that clip on mobile, cover gameplay, or lack proper pause/win/lose states. This Skill provides a structured workflow and reference checklists to design readable, responsive, genre-appropriate game UI. ## Core Features & Use Cases - HUD and Menu Design: Covers gameplay HUDs, pause/resume, settings, fail/retry, win/milestone, loading, and touch control states with defined layout zones and hierarchy. - Quality Checklists: Ships reference checklists for UI quality, HUD readability, responsive fit, and mobile input that must be verified before work is considered complete. - Asset Generation Guidance: Directs use of companion image and 3D generation skills for icons, logos, menu backgrounds, and diegetic 3D UI props. - Use Case: A developer building a Three.js arcade racer uses this Skill to redesign the HUD with fixed-width speed and timer displays, safe-area-aware mobile touch controls, and pause/fail screens that match the game's visual style. ## Quick Start Use the threejs-game-ui-designer skill to redesign my game's HUD and pause menu so they are readable on desktop and mobile.
