WebGL experiences & accessibility

Hello,

I am looking for some thoughts on how to address accessibility on webgl
experiences. For reference, what I mean by a webgl experience is something
similar with what Netflix did for The Witcher
<https://witchernetflix.com/en-gb>.

What would be the best/impactful approach:

   - Provide a separate more linear/simpler experience while maintaining
   the main user flows?
   - Or provide "Accessibility Settings" where users can change font style
   or enable/disable animations etc? (this idea I took from games &
   accessibility)

Any feedback would be appreciated!
