The teleport glitch I'm using in this speedrun is called a "Zip". It's a frame perfect trick requiring to move forward at a specific timing while blocking and walking.

To make it harder, you have to press forward for a specific amount of frames, depending on when you started moving forward.
The goal is to release forward after the block animation reached exactly 139 frames.
Speedrunners are using a metronome to hit that timing. I'm using a 107.5 BPM and try to time my forward input/hold the key for 4 frames at the 5th beat.

We also are using another variation of zips to "kill" bosses, called "Megazips". It's a zip followed by another W input after 12-14 frames after releasing the initial W press. It's really hard to do it consistently but in this run I got all of them really quickly.
