Notes:

Take advantage of the ledge-filled shaft to increase your survivability.

But beware:
You can only grab ledges 6 times in a row. (That is as long as you don’t land properly.)
And if you dare to make a 7th attempt, your grab will automatically fail and you'll be sent tumbling down to your doom.
This is true on all stages, with all characters.

So remember to reset the grab-counter mid-climb with Neutral-Getup, Getup-Roll or Getup-Attack.
Now, when it comes to which kind of getup is more consistent: it kinda depends on the character.
