Building a playable island game in under an hour with GPT-6 Astra and Tripo CLI
The author had Astra build a playable prototype in Codex, then used Tripo to generate 3D assets and rig the character, replacing placeholders to finish the game LUMEN ISLES.
I built this game in under an hour with GPT-6 Astra and Tripo CLI. I asked Astra for a small, cozy island adventure with a lighthouse, little cottages, lanterns, and a world worth exploring. The workflow was surprisingly simple: → Connected Tripo CLI to Codex. → Had Astra build a playable prototype. It worked, but the placeholder models were pretty rough. → Used Tripo to generate the 3D assets, rig and animate the main character, and replace the placeholders. → Had Astra integrate everything and polish the lighting, movement, camera, and lighthouse finale. The result is LUMEN ISLES, the actual playable game you see in this video.
