That was a tricky situation for me too, man...or woman. Anyways, I could tell you how I started it along by pure chance and managed to get it within' my first tries. It might not even work for you but whatever. Another option is the boring, less frustrating answer the other person gave but what's the fun in cheating that way?
Now, how I did it. It wasn't too long ago so I remember it well enough. To get past this stage, I recommend that you go to the farthest base block (the lowest you could go and the level you start at) and pull it out. Shimmy to the next one and do the same thing but don't make it incapable of continuing.
The rest is mostly luck and wits. Remember the techniques you learned, too. And the most helpful thing, seriously, is the fact you can hang on blocks and work around them. Because even if you pull yourself off the edge of a block, you can still make it to the spot behind the block you pulled if there was one.
