Open original on X

Back in July, I made an AI video imagining what a samurai game could look like. Now, thanks to Opus 5.5, it’s actually playable. In less than one hour, Claude built the game using only that original video as reference. Then I spent another 12 hours iterating on the gameplay and visuals with GPT-6 Astra to push it even further.
