If you see videos online
showing more moves, this is the reason.
The videos are outdated because the video creators make them when the
levels are first released. The studio monitors all levels when they are
released and they check to see how many players clear a specific level and how
long it takes for them to clear it. If it's too easy or too difficult
they will "tweak" the levels a bit. The video creators can't
keep up with the studio changes so you are still only seeing the first video
