Hovering

Hovering was originally a technique in Super Smash Flash 2 that could be performed by. It was performed by jumping or going off-stage and then holding the jump button at any point while the player is in the air. This technique was very similar to floating in that it allows the user to fall slower and move faster sideways by holding the button. Unlike floating, however, the player cannot simultaneously hover and attack, instead cancelling the hovering until the attack is over. Tails was able to hover for an indefinite amount of time and was not restricted by his amount of jumps remaining.

For unknown reasons, this technique was removed entirely in the Beta 1.0.3 of the demo. Although, one theory is that it made the character's recovery too overpowered, as it practically allowed him to recover from anywhere he was sent thanks to the low fall speed [which could be lowered further by tapping up] and indefinite amount of time he could hover. This was a similar case to Gliding back in Super Smash Bros. Brawl, as it did not return to the subsequent title possibly due to the same reason.
