Rocket is a power-up that can be used to fly above the terrain and dodge sawblades and traps. However, it cannot avoid lighting strikes and rifle shots.
When activated, the player will start to fly. If he presses on jump during flight, he will move up a bit. Note that you can press "up" a maximum of 3 times quickly before it has to cool down.
When rocket is about to expire, it will start flashing. When it expires, the rocket will explode, killing you and any other players close to you.
You can throw sawblades, traps, and shoot from the air whereas using shield, balloon or speed will deactivate the rocket. Activating the rocket power-up when you are using rocket will reset the explode timer.
