Spring Jump

Spring Jump (スプリングジャンプ, Supuringu Janpu) is 's up special move in Super Smash Flash 2. Sonic jumps off of a spring, launching himself into the air. When used in the air, the spring becomes a weak projectile that meteor smashes if it hits someone on the way down. Unlike many other up special moves, Sonic's does not leave him helpless, allowing him to attack immediately. This move, which acts as Sonic's recovery, provides decent vertical height. However, it provides mediocre horizontal recovery even when angled to the left or right. Also, after Sonic uses this move, he cannot use any of his special attacks until he lands (except Bounce Attack). He also loses the ability to use his midair jump even when he uses the grounded version or when he does not use it while performing the move in the air.

Trivia

 * There was a glitch in which if Sonic uses any attack (with the exception of his down aerial) immediately after using his up special move, he can use his up special move again, making him have an infinite recovery. This was later fixed in the v0.6 demo.
 * Much like 's Spin Attack and 's Super Jump Punch, Spring Jump was improved, in terms of horizontal recovery, from its Super Smash Bros. Brawl counterpart. It allows Sonic to move freely during both the rise and the fall, unlike SSBB, where he could only control the direction after peak height was reached.
