rocks, locks, and invisible blocks
All of the L jumping is just normal L jumping. The morphball movement is kinda weird to explain but really just copy what everyone else does, you want to rock left to right in some sections to turn tighter or have more momentum at 'uphill' parts. for the pirate dash, you should be dashing basically as soon as possible and pressing R instead of letting go of L for the first dash, so you can get speed but keep the lock on. 4:32 isn't easy to achieve. You'll not only need to have solid play but really understand how to get the most speed out of all of your jumps and dashes. (which just kind of comes from practice).
