What's the trick to the maze?

Hint 1 of 9:

It's mainly a matter of trial and error, unfortunately.

Hint 2 of 9:

Your basic goal is to get up to the second level of the ship.

Hint 3 of 9:

You'll have to crawl through the turbolift shafts when they're free.  That
means that you may have to duck in and out of the shafts until the turbolift
car gets out of the way.

Hint 4 of 9:

You should notice that some levels have more than one turbo shaft.  Those
extra shafts will help you reach your destination.

Hint 5 of 9:

You basically want to go up whenever possible.

Hint 6 of 9:

The exact directions follow if you can't figure out the maze for yourself:
"North" (N) is to the back of the screen; "South" (S) to the front; "East"
(E) is to the right; and "West" (W) is to the left.

Hint 7 of 9:

N. E. N.  Enter the shaft and go to level 6 (up two doors).

Hint 8 of 9:

S. W. N. N. E. N.  Enter the shaft and go to level 4 (up two levels).
