"Create" is doing a lot of lifting here. As you (and the original author) mentioned, almost everything was assembled from downloaded free assets and libraries. Almost everything is a copy-paste. The Fable part is linking and debugging until it doesn't crash.
The main value proposition of LLMs is to wash the credit away from the giants and take it for yourself.
I wish we would give credit to Kenney [1] for making sick asset packs, mrdoob for making THREE.js [2], etc. than Fable for running curl/wget...
