Rocket Top

The  is a component of the rocket you must build to escape the planet and so win the game.

The complete rockets consist of a Rocket Engine, 5 Rocket Tanks and 1 Rocket Top. After completing it, you must activate the Rocket Top with the E key to fire the rocket.

WARNINGS
When you activate the rocket it will take time to charge up, in this time the strongest monsters (Heavy Particle Bird, Lava Bats, Lava Spiders, Hellhounds) will attack  you. When the Rocket has charged to 50% it will ask you to enter the Rocket, if you are not protected till then the monsters will kill you, because you cant move any more.

You need to be sure that way up is open. Look for floating islands in the sky and make holes for the rocket if needed.
