Is your feature request related to a problem? Please describe. For those that have limited vision or visual impairment we don't provide any screen-reader support. We should absolutely provide this to make sure as many people as possible can enjoy the game.

Describe the new feature you'd like Add screen-reader support and then test it with the Accessibility tools provided by browsers. Mostly this will be aria proeprties, but there may also be some amends to make elements focusable, with tab indexes etc also being implemented.
