Are you sure this is 1.0 coded? Or does it belong in Older Mugen?
Also, your BGCTRL shake is a bit odd, the whole floor doesn't shake a part of it remains flat, which is incredibly awkward. Also, your contrast in sprites (namely the rocks and background stone) in comparison to your background is clashy. The background is very blurry and the items in front of it are not.
Something about your floor is still bugging me, perhaps a wrong delta. It moves awkwardly when the characters walk/jump.
The layerno1 rocks could also use the blackjack method making them slightly transparent. Your floortension and vertical follow could use an adjustment as well.
Also just opinion, your fog could be raised a bit higher and have a bit more trans added to it, as well as some lighter shadows.
Your sprites aren't cropped, and you have huge images placed without proper indexing. If you activate transparency you can see a bunch of white pixels, this is improper indexing, some of your colors are being subtracted. Perhaps you could RGB/Jigsaw the background?
It also looks as though for your "light" sprite you used pink as a 0 color with all of that excess black, making the image rather large and computer intensive. Perhaps you could just have black as your 0 color and use trans effectively.
Also, that fog looks familiar, I'm not sure whose it is specifically or if you made it I apologize, but you should credit them.
