A comprehensive guide covering the fundamental principles of interactive entertainment design.

This framework outlines the 'Hook Model' (Trigger, Action, Variable Reward, Investment) for building deeply engaging, habit-forming product loops.

This skill generates a single, full-bleed, looping motion composition using only inline CSS animations.

Ideal for briefs requiring sophisticated 'motion design' or 'animated hero' assets.

A skill designed to generate cinematic, short-form video clips (3-10 seconds) suitable for marketing reveals, product teasers, or ambient loops.

Ideal for creating impactful, bite-sized visual content.
