Stage 1
The Pole Maze is similar to a less challenging obstacle that appeared in Stage 3 in a couple of early seasons. In that version, they had to pole vault over the water, but there was no maze to move the pole through.
The Jump Hang was previously one of the toughest obstacles in stage 1. As a more difficult version, the Jumping Spider is, well, really difficult. It's hard to tell sometimes from the editing, but it appeared that the majority of Stage 1 competitors went out on this obstacle.
Both of the American competitors sponsored by G4 went out on this obstacle, along with most competitors this season. One competitor, Yoshihiro Minami, fell and somehow managed to jump backward onto the trampoline, do a somersault and land safely on the platform. He then tried again and cleared the Jumping Spider, although unfortunately did not complete stage 1.
I wasn't crazy about the Curved Wall because most of the structure was wasted: there was this big curved wall, and everyone ignored it and just ran up the edge. They seem to have resolved that problem with this redesigned obstacle. I do feel compelled to point out that the curved wall in Halfpipe Attack is not actually a half-pipe.
