Hi FreeCodeCamp. First of all, Thanks for this accessible game.
there are some issues that I've pointed out.
first. I'm a windows user. and using NVDA screen reader. but in this game, TTS only works with native screen readers, that is narrator in my case. but narrator is not responsive as NVDA is. so, it would be better to give option to the user about choosing the screen reader. specially if user is using windows.
second, currently, it's not possible to change the speed of the TTS from the game. it is better to have this option for the users so they can play the game on their own speed.
third, there was a question in HTML about ins tag, but TTS wasn't speaking the options of that question.
fourth, there could be some shortcut keys to control the volumes of the sound and music. for example, Page Up for increasing the music volume. Page down for decreasing the music volume. etc.
and lastly, in the settings, there should be a slider with percentage in the options like text speed bar, sound volume, and music volume etc. when we increase the volume, it could say, music volume 50%.
Thanks. and again, a lot of appreciations for this accessible video game.
