Certain characters can glide (Charizard, Pit, and Meta Knight) by
performing a jump with the jump button and holding it down. The
character will then get into a gliding stance and fly forward,
descending slowly. By pressing down or forward you can tilt steeper
down into a faster descent, and by pressing back or up will slow
you down to a snail's pace and you will eventually stall out. You
cannot change direction during a glide.
