That's one of my favorite parts in the game! It feels so good once you've mastered it because you'll be blazing through that level with ease as others stare in amazement of you overcoming so many obstacles so quickly without a problem. Be warned though, the part after that is argueably harder and you got to make sure you have the key for that level! There is also another part towards the end of the level that took me awhile to figure out, but once your past that it's time for the final boss (who can be a real pain).
