I think this site is not good for it because it's mostly it can be devs producing games in jams, where the time limit means there's little time for accessibility implementation.
And in a way, that's part of the problem - that it's so time-consuming that devs often can't do it. There need to be better ways for devs to feel able to support a11y, extra tools for engines and the like. It's unfortunate that in some cases I'm seeing the engines themselves not providing key features.
What I would love to see for game jams is that after the submission deadline, there's some way for devs to add in missing a11y features. But when devs are more practiced with it, they would probably be able to do it as they went because they would know the implementation patterns. Particularly where in some cases, the a11y feature is actually the absence of a game mechanic, or is a handy feature for testing, and hence feature-flagging those mechanics straight away means you only need to provide the mechanism to set the flag. I would love to see more discussion about good practice like this.
