First time I did it, I created stairs all around the sides, going up about 5 cubes of height each time. It took forever and I was terrified of falling the whole time. Then I hit the lip at the top and couldn't move. Had to fall off and re-start. Got all the way back up to the top, and the controls froze. Had to restart. Finally did it on the 3rd try. Then had to do it all again on the next section
Now, the EASY way - you send one of the snakes up to the top. Make a ladder out of the other one. Stand on it. Use middle button to connect the two snakes. You rise up as if by magic
