Game Objective
--------------
The objective of the game is to complete all 16 screens in sequence
without using passwords. To complete a screen, you must collect all the
diamonds on that screen. Some diamonds are available immediately, 
but most are obtained by pushing two boulders together.



Mystery Objects
---------------
Some boulders have question marks on them. These convert into one of
the four mystery objects. 

An hourglass increases the time remaining by 50 seconds.
Four magic potions give an extra life.
A bonus score gives 500 extra points.
A key swap reverses two or all of the movement keys.

These mystery objects do not have to be collected to complete a screen.



Other Maze Inclusions
---------------------
There are also black boulders, which cannot be converted into
diamonds, but are obstructive. Keys are pushed into doors to open
them, but they must be facing in the correct direction (either left
or right). Monsters prowl around some screens. Contact with a monster
leads to loss of a life. You start with four lives with 500 seconds to
complete each screen.



Password Feature
----------------
Each of the sixteen screens has a password, which is displayed at the start of
the screen. To start a new game at a screen which has been previously
reached, press the P key on the title screen, and enter the password.
