Thanks, Neil. I think it’d be useful to have this information around somewhere prominent, because I would be willing to take the time to make a game accessible. It seems more worth a formal document, but that seems like potentially even more significant of a time investment.
In my game, some very important text was lumped together as letters, so it created nonsense words. I found it was not to bad to write out conditional text that lets you space letters or, as you mentioned, put stuff between asterisks.
Ironically, I thought abbreviating Red as R and Yellow as Y was almost certainly easier and had no downside.
Thanks for the screen reader information!
