The danger zones get more, erm, dangerous, as the game goes on, and especially when they are right on the edge of the hole where you'll be dropping down. To make things worse, some of them even move along the platforms, and get in the way of the hole to make it even more difficult to jump down. Yikes. Simply take your time, have some patience, and wait it out. You might want to go for big scores and big combos by sliding down multiple platforms at once, but it could be an untimely end for your high score.
