I give up on this level. I have tried for ages to reach that little moving platform in the volcano, and to stay on it without getting killed... and when I finally did it, I had to find out that this platform is just there for nothing, since it doesn't get you anywhere and it is impossible to reach a checkpoint with it. I don't see how this level is possible, even though some people have completed it.
EDIT: I MADE IT. That is one of the hardest levels ever... great.
