Voyage of Valkyrie documentation.

Scene:   The island of Fugley.

Aim:     Overtake all 10 castles which are guarded by various warbirds.

Details: You start from your base-mountain and from there,
         map the island by flying around it. Be careful not
         to collide with any mountains! Note that you can't
         see what's behind a fog bank so you may have to
         fly through it. There may be a mountain slope or
         pass to crash or fly into. If you want to refuel,
         just fly back to base and press Q or R.

Controls:
         Navigation mode is set by <CLEAR>.
            In navigation mode, use the arrow keys to rotate your ship.
            Push <SPACE> to move in the direction you're facing.
         Combat mode is set by <ENTER>.
            In combat mode, you use the numeric keypad to aim the cross-bow.
            Picture the keypad as having 8 arrows (7/8/9, 4//6, 1/2/3) 
            with a central firing button (the "5" key). 
            You must hit a bird exactly in the chest for it to die.
