#prejump 2

Small but cool optimization suggested by @!!cerpin. If you prejump dash after the fireball to kill the enemies outside GHusk, you'll clear the ledge at the end of the tunnel. I recommend either jumping at the divot in the ground marked in red or dashing at the notch in the ceiling marked in yellow.

Some things about this:

• All of these advantages assume you normally wait until landing to dash after the tunnel, which you typically would to make sure you get the geo
• Buffering the next dash out of the tunnel with the normal movement will have you dash above most of the geo. Air dashing means you can't dash early, so you can buffer the next dash on landing
• Clearing the ledge lets you dash again a little earlier and exit the room faster; looks like roughly 2f/0.04s from my timing
• Clearing the ledge also has you land a little further right, allowing you to pick up a few extra geo on average

Nice prejump with transition storage. Saves ~.25s over the normal strat.
Timings are :

• If you get the oob early and transition storage late (as in video, optimal), 3 steps then full jump
• If you get the transition storage early, 4 steps then full jump

Don't forget to adapt your timing to veer back after dodging leg eater.
First part of vid is strat as you would see normally, second part is zoomed out with camera follow and hitbox so you can see what's going on
