Have you tried Rive? It seems to have a lot of potential for game development.

It's a UI authoring toolkit, you could do entire games in it I suppose, but you'd be fighting against it, rather than being helped by it.

Better to go the route of doing Spine2D animations then leverage a real game engine like Godot or Unity and load the animations there.

But then you're essentially back to "traditional game development" which is very different from what you could do with Macromedia's Flash back in the day.

I think this was also true of doing game development in Flash. Some people here might be looking back at Flash with rose-tinted nostalgia glasses.
