No u2014 one jump per landing, but holding the button extends the arc.

Question 2

How do I tell blade heights apart?

Accepted Answer

Low blades sit on the floor line; head-height blades float clearly above it.

How fast does it get?

Accepted Answer

About 13 px/s per second, so after forty seconds you are moving roughly twice the start speed.
