"lift off"Rocket Jump is an upgrade that allows the player to jump higher from the ground (but not off enemies). In addition to this, jumping creates an explosion on the ground beneath, killing any nearby enemies and destroying nearby blocks.
The exact area is about 3 squares wide, 1 square down, and 2 squares up, totalling to a 3x3 square. Rocket Jump's ability to destroy blocks beneath the player often forces the player to move faster, especially in World 2. In addition, the instant kill of enemies 1 block around the player occasionally serves useful when being pursued, especially by Ghosts and Eyes.
Rocket Jump has to chance to appear as an upgrade after completing a level.
