# Install "Video to Game"

Treat a short gameplay video as the design document: study its frames, palette and cuts, build one playable Three.js game around its one mechanic, then prove it with side-by-side frames and a recorded keyboard playtest. GameSkill tested the whole loop with code-made assets; the author's fal asset step is optional and paid.
