I Built a Sekiro Clone With This INSANE GPT-6 Astra Workflow

I've always wanted to build Sekiro's combat — katanas clashing in showers of sparks, Mikiri Counters, Lightning Reversals. So I built my own 2D version with GPT-6 Astra in Codex, and the workflow turned out to be the real story. Astra connected the whole chain: designing the game, writing its own image prompts, generating the artwork, building models in Blender through an MCP server, writing the code — and then actually playing the result to see what was broken. That last part is what makes it work. It doesn't just generate. It looks at what it made, notices the platform is too high to reach, and fixes it. Build something. Look at it. Try it. Fix it. Repeat.
