Dash canceling is a technique in Super Smash Flash 2 that is performed by dashing either to the right or left and then pressing down and the opposite direction. This will make the character dash forward and quickly pivot with a crouch. This crouch pivot from a dash acts like doing a backwards-wavedash. This technique is useful for spacing and gives the player neutral options. This technique is best performed when dash is mapped to its own key. Characters with great initial-dash momentum gain the biggest advantage while performing this.
