Godot is a game engine that is open source. It is pretty popular with indie game developers but not only is it not very accessible but it is not easy to develop for screenreader support. Currently there is development that will appear in a future release that supports screenreader support better, but this project aimed to provide a means to branch that gap for developers. In other words - this project exists to help sighted developers make more accessible games. hope that explains better.
One thing that kind of sucks is that there were a few gaps in my model that I discovered while implementing it in my own game. it works quite well but there’s a few bugs I never got around to fixing because of life. but there are several forks on github that probably address these issues
