OUTLAW (16K ZX-81)
by Chris Colley of Cambridge, Cambridgeshire
from Your Computer (August 1985), page 100

The idea is to get from your hideout at the bottom of the screen to the
castle at the top, steal some gold and return with it to your hideout. In
between, you have to negotiate the changing doorways in the outer walls and
avoid the patrolling guard. You have to make the trip 12 times in all and
each time the game gets slightly faster.

You may wait in a doorway for a passage to clear and in this time you may
find the gap changes and a wall is built on top of you. You may use this to
your advantage since, when you move, there will be two gaps in that wall
until the next change. Be careful not to forget your position while you're
hidden though.

The machine code may be stopped at any time by pressing shift with P, 0,
Newline or Space. If the game is too fast, the speed may be changed by Poking
17480. This is initially set at 16 and the delay is caused by the computer
counting up to

  (PEEK 17480  SCORE) x 256

Therefore, a number lower than 16 makes the game virtually unplayable in the
later stage, while a number higher than about 30 makes it tediously slow in
the early stages. If you require a challenge, cut your number of lives by
Poking 17435 with the number of lives you require.
