When you bash something, Ori gets a boost of speed which slowly disappears. But it is actually possible to preserve that momentum by releasing directional inputs after you released your bash.
That momentum won’t decrease until you touch the ground so you can preserve it longer by either using the feather to glide, aerial jumps or a combination of the two. Hammer and Sword up slashes as well as Shuriken and Flap also preserve the glide effect, making you go further. You can also use Pause Floats in order to preserve the glide effect.
