@MarieH1665 Not only do you have to upgrade ALL the parts to fully upgrade your ship, but if you look to the side of the ship screen, you'll see [random number]/12, you have to get that number to 12. then fully upgrade all of the parts.
Protip in zelda level: At the old man stage, destroy the 4 crstals then attempt to kill him, he'll split in 3 and just destroy him, now he turns into a giant, he ALWAYS follows this pattern, ALL DIAGONALS, ALL SIDES, FALLING ROCKS. its easy to dodge making it easy if you know this.
For all people stuck in the water pit trap, click the left spike, and left again
then to the gun. you should see the gun falling in the pit, ignore it. then HIDE behind the green crate. click on yourself to whistle. do it again to make the guard confused. slide under and climb the pole and knock the guard off. then get the gun AND SHOOT THE GUARD! you should be passed the water hole trap. + to keep this comment alive!
Soldier: Sir, the man in the sports car is driving and helping kill the zombies invad- General: NO! JUST KILL HIM! Soldier: But he isnt killing any huma- General: NO JUST GET OUT THERE AND KILL HIM!
