When performing the Window Jump, Tails thrusts himself forward while tucking in his arms and legs and twirling his twin-tails, thereby increasing his horizontal speed to gain distance.
In gameplay, the Window Jump is useful for crossing larger areas when sent flying into the air or preserving Tails' momentum when falling to the ground. Additionally, the move will not cancel the momentum Tails receives from Boost Mode. By comparison to other Long Wind Jumps, the Window Jump's movements have a slight upwards inclination, but it does not last very long or lets Tails damage foes in his flight path, meaning it leaves him vulnerable to enemy collision. Also, the Window Jump can only be pulled off after Tails has been launched into midair by gimmicks like the Spring or Ramp.
Sonic Advance 2
The Window Jump first appeared alongside the other Long Wind Jump maneuvers in Sonic Advance 2. To perform the Window Jump in gameplay, the player must press right/left on and the R Button at the same time after being launched into midair by gimmicks. The direction Tails heads in is determined by the direction pressed on .
Sonic Advance 3
In Sonic Advance 3, the Window Jump returned as Tails' Long Wind Jump maneuver, and one of his Special Actions. In this game, Tails can only use the move when having Sonic as his partner. To perform the Window Jump in gameplay, the player must press the R Button after being launched into midair by gimmicks. To launch the Window Jump in a certain horizontal direction, press left/right on when pressing the R Button. Pressing the R Button without selecting a direction launches the Window Jump in the direction Tails faces.
