i recently just got back into speedrunning this game and alot of strats have developed since i stopped. Can someone explain to me the strat where you dive upwards after a wall slide to clip into the flag as seen on level 17 and 27.

so it's pretty precise, but when you get to the corner of the level, you dive and then smash in quick succession in order to clip your hitbox into the flag. i find that it's easier to do in 27 than 17, but both are easy when you get the hang of it. you just need to hit the keys pretty quickly.

and on 27 you have to go to the top part of the level and unlimited wall jump up the wall, and then walk over to the spot where you clip.
