It won't freaking let me go back to where I was before I came in this area without double jump otherwise I wouldn't be asking. Where exactly am I supposed to wall run to exit?. Every possible way is too far up to reach without double flip which I don't have. Don't think I haven't tried.
From the area where the mud slides starts, you have wall run walls that take you back to the area entrance. I think it's on the left when facing away from the mudslide. You go from one raised platform to the next. You do not need double jump or anything else to get out of there.
