I know the last update was several years ago now, but have you considered adding the controls menu back in? If not I totally get it, my understanding is that this project was not well supported. But this is my favorite way to play spelunky, it's an amazing mod with all kinds of great QOL improvements, and it would be great to see it with that extra level of menu polish.
The old controls menu was hardcoded in the old netcode system, which I swapped out entirely.
See my comment immediately below for the project’s general situation
