Frankly this still doesn’t seem technically challenging. It does seem like a different sort of design challenge though to get all of the little mechanics correct. This isn’t like inventing a new algorithm though. I suspect implementing this is more like constantly iterative tweaks and “feeling out” whether the controls are right.

The end result looks complicated but no sort of specialized engineering skill seems necessary to achieve the result. Just grit and design talent.

I think you're discounting too much the level of skill that 'grit and talent' requires. Cos it is exactly inventing a new algorithm - just not via mathematical proof or vigorous formality.
