I gave Claude Opus 5.5 just 3 prompts to make BLOX FRUITS in Roblox, and it built a full fruit-power open-world RPG called Seedfall: fruits with real powers, bosses, islands, boats, swords, quests… and a full DRAGON transformation. 🐉
Game:
ForgeGUI:
Claude built everything inside Roblox Studio through MCP, and ForgeGUI let it make its own 3D models, effects and sounds. Every name and every piece of art in the game is original. Watch how each prompt upgrades the game, from version 1 all the way to the final build with the Dragon Fruit and the Hollow King boss.
