A few days ago someone on my discord server asked me how to configure keys in an exported cart and I didn't figure out how to do it, nor did I find any information about it anywhere...

So I assume there's no way to do it right now...?

Just letting the player access the Keyconfig screen from the controls screen would be great.

And saving the config after each session :)

I think it's something that can easily affect user reviews in external sites, Itch.io, Kongregate, and so on, and also help with accessibility.
