BackJumps into Perma-Sprint. If ever you wanted to see just how powerful Perma-Sprint is, here you go.
The start here is to pick up a Mortar weapon early in the stage. Then the BackJumps are used to reach 4+ pixels per frame, so that we can peacefully charge up Sprint mode while outpacing the camera. We go for a swim right after, triggering Perma-Sprint and you can see what that means for our hero. We even found a door we can simply clip through because the terrain there is hollow, and Perma-Sprint is so fast we can pick up the Mortar in there and continue on our merry way all before the camera catches up.
After that, I'm not entirely sure what precision planning is happening for the last two victims. Disorganized notes, I say. It reflects where I stopped in my TASing of this particular stage as well.
