Boundary Hopping/Wall Hopping explanation

Mechanics of Wall Hopping + Boundary Hopping: You can do short hops along walls (which I define as things you cannot long jump into) and along the boundaries of the screen by doing short hops (neutral dpad + b) facing into the wall. When you short jump into a boundary or a wall you will land there if and only if you jump in a direction that is heading into the collision. This means perpendicularly or from an angle. However, if you are jumping parallel to the direction of the collision where you land, you will fall.
