I made this game in ~5 days with Opus + GPT -- tried to see how far an “almost 100% AI” workflow can actually go

I spent around **5 days** making this game. I know that saying something is “100% AI” definitely isn’t a sign of quality, so my goal was to find out: **how much quality can I actually squeeze out of AI?** The main setup was **Opus 5.5 + GPT**. GPT was mostly responsible for **image generation / concept art**, while Opus handled basically everything else: **game logic, 3D models, shaders, sound, optimization, UI, balancing, implementation, etc.** My own role was mostly coming up with the original idea, testing things, giving feedback, approving the first concept-art direction, and deciding what was good enough to keep. I actually posted about the game earlier while it was still in development, you can find that post in my profile if you want a more detailed breakdown of the process. In my previous post I said that the **water shader was mine**. Well... not anymore. By the final build, Opus had completely rewritten it while optimizing the game to maintain around **60 FPS even on…
