Codex turns concept art into game levels

This is the kind of workflow that makes AI coding tools feel immediately useful: not replacing artists wholesale, but removing the friction between concept art and playable scenes.

• –Asset-sheet decomposition is the key move; it turns a one-off image into reusable game parts
• –Codex is being used as an assembly agent, which is a stronger demo than generic "write code" examples
• –The result is best viewed as fast preproduction, not final art, because consistency and polish still need human direction
• –The $20 framing matters: these tools are cheap enough for solo devs and small teams to iterate in hours instead of days
• –The combo of image generation plus code execution points toward a new standard workflow for prototyping games, UI, and interactive mockups
