Maybe the dash/double jump was what was intended, but
I found this technique worked out so much better for me. Thanks for the tutorial!

You just dash then double jump under the pillar in the opossite direction, is the intended way and even easier than this

That's...certainly one way to do it.

There is also a relic that makes you weight less (initial area after obtaining spider web move). It's mostly pointless, but you slightly float up when doing combos... can be handy to break platforming areas.

1. Use Lars dash to get to the pillar
2. Dash under the pillar
3. Use second ability of No 7
4. Climb the flat wall of the pillar.
5. Repeat from point 1.
