What about a Braille reader and using Inform7 on a Linux command-line system? Seems to me it would be a lot simpler than using a screen reader. It would also be a great way to play interactive fiction.

There are frameworks for most popular programming languages, which would let you use NVDA with any supported text editor. It sounds like you're using some kind of Graphical Interface to enter the text? (Sorry, I'm a sighted programmer so I'm extremely familiar with how difficult it can be to parse text on the web, unfortunately I'm not familiar with many of the existing products to do it for users. The ones I've seen are terrible.)

I've written my own simple, interactive fiction frameworks in Ruby and Python in the past but I'd recommend using a more mature framework like PyF or others that let you enter the gameplay in simple markup like XML, YAML or Json. There's also Inform7 for non-programmers but I'm not experienced with that.

Here's a link I found with some good info on what's out there now and it appears to be Windows focused: https://gamedevelopment.tutsplus.com/articles/interactive-fiction-text-adventures--gamedev-9996

Good luck, it's a fun hobby.

Tads3 works. But you'll need to use the command line compiler tools yourself, rather than use the IDE it comes with.
