Curious enough, I tried the same prompt with Qwen3.6-27B.

One shot produced a game with no sheeps. I had to told it to fix two bugs then.

Overall, the graphics and games seems good enough and better than most of the closed models that were shown. However, not surprisingly, falls short of Fable.

I've put the index.html and open code session here:
