build-a-game- Description
- Take someone from a one-line game idea to a finished, polished 3D browser game live on the web, using the 10-step pipeline that built LAST CALL (a 25-minute cozy horror game made entirely with Claude Code). The steps are lock the story, build a visual debugging tool, pick an art style and turn it into a design system, cast voices with ElevenLabs, make a talking-character demo, build a playable vertical slice with a small agent team (a critic, a genre director and a narrative director), playtest it, build the rest, polish, and deploy it to the host they choose (Hostinger, Vercel, itch.io or any static host). It asks the user clarifying questions at every step instead of guessing, and resumes from docs/HANDOFF.md in any new session. Use it whenever someone wants to make, design or build a video game, browser game, Three.js game, game prototype or vertical slice, or says "I have a game idea", "help me build a game", "continue my game" or "next step", even if they never mention a skill.
