Hello,
I would first like to thank you for implementing an accessibility mode for blind people. It is really appreciated and really well done.
Here I would like to report a few problems and make a few suggestions. Let me know if GitHub is a better place to continue the discussion.
First, repeating text.
There is currently a small problem with all story text in game. The TTS starts reading a message, and then mid way stops and starts again, this time finishing successfully however so it is not a huge problem.
What I suspect is happening here is the text appears on screen, TTS starts reading, and then the text finished scrolling and is now fully available so speech interrupts and restarts to read the completed text.
I have no usable vision though so this is only my guess. If it is indeed the case, it would be better for TTS to start reading only when the text is fully available and thus avoid this problem. If my explanation is not clear enough, I can submit a recording demonstrating this.
Second, it would be really nice to be able to spell any text with left and right arrow keys moving letter by letter, for example. As it stands, with many TTS engines, git add filename and git add <filename for example sounds exactly the same.
That's all for now, and once again I thank you for a very well designed game and for keeping accessibility in mind.
