Finally! Multiple platforms that you can walk on them!

Well, I think we can do it if we make a special jump looping activated by a next.the next frame will have positive dvy with a suitable number of frames after it.this will leave frame 212 free.
now we can change the wait in frame 212 to 0 and make the next go to a specific frame that has a dvy 550.
I hope this works.
