What problem does it solve? Game prototypes often feel flat and lifeless because interactions lack feedback, and teams struggle to define a repeatable core loop or pick the right engine. This Skill turns a game concept or a dull prototype into a defined compulsion loop with visual, audio, and haptic feedback on every action. ## Core Features & Use Cases - Core Loop Design: Defines the 30-second loop with Trigger, Action, Variable Reward, and Investment, grounded in player psychology (Flow, Self-Determination Theory). - Juice Injection: Applies the Trinity of Feedback (visual, audio, haptic) to every interaction using a concrete checklist covering squash and stretch, particles, screenshake, freeze frames, and pitch variation. - Engine Selection: Recommends between Unity, Unreal, Godot, Phaser, R3F, and Bevy using a decision matrix based on platform, team size, and 2D/3D needs. - Use Case: Your mobile platformer's coin pickup just increments a score silently. Use this Skill to get a concrete feedback plan: particle burst on pickup, a one-shot sound within one frame, and a light haptic tap, without breaking the 60fps budget. ## Quick Start Ask the assistant to design the core loop for your game concept or to add juice to a specific mechanic that feels flat.
