2. Hold down the fire button (
). Keep holding until done.
3. Spam the jump button (
Repeat step 3 until the achievement is completed.
The reason this works quicker is because when you jump against a wall you perform a wall slide. This keeps you in the air, but if you repeatedly jump, the jumps are shorter and quicker, which will earn you the achievement 3-4 times quicker than just sitting there and pressing jump away from a wall.
