Gambling aside, the median quality of a modern mobile game is worse than what we had on newgrounds.
NG didn't have multiple 500MB downloads, buttons in the wrong place, pointless currencies. More importantly NG artists actually cared. I understand why Apple killed Flash, but what we got in its place is not better.

In retrospect, it turns out the reasons were a load of bollocks. Modern web is 10 times more bloated than Flash ever was, and nobody cares.

WebAssembly is better compilation target and runtime than Flash ever was. Many languages can compile to WebAssembly.
I think what you want is an authoring tool like Flash. Why not make that tool? Or if you don't want to make it, Rive's a pretty good animation engine. You can make games with it:
