This is a good article. Despite what others have said, it has a concept that it expands upon in a way that makes sense. There's not really anything left to expand upon, and you did expand on the concept. Don't let people suggest that the ideas like the dialogue and use with vision impairments aren't expansions, because they are definitionally expansions on the concept.
The only complaint I have is that it feels too videogame-like, but that's the point of the article, so it's just something I personally don't like and not something wrong with the article.
You deserve this upvote. Good job.
