The final goal of the game is to free the captain'soul.
In order to achieve our aim we must locate a secret room
(that will appear on the last deck of the ship) but first
WE MUST COLLECT 4 pieces of a map(which I suppose in the intention of
the programmers holds the location of the chamber itself).

THE PIECES OF MAP ARE : 1) DECK 1 NOT GUARDED AND EASY TO GET
                        2) DECK 4 NOT GUARDED! LAID ON THE TABLE OF A SHIP-HALL BUT YOU CANNOT TAKE IT UNTIL 
                                  YOU'VE DONE SOME THINGS!(YOU NEED SEXTANT, COMPASS, TELESCOPE )
                        3) DECK 5 GUARDED BY A GHOST WITH a SWORD(ITEMS NEEDED CANDLE LARGE BOOK BELL)
                        4) DECK 5 GUARDED BY A MERMAID(items needed MIRROR, PEARL,COMB)

 IMPORTANT : HERE YOU'LL FIND THE SOLUTION OF AL ROOMS BUT DUE THE NATURE OF THE GAME,
             IT'S UP TO YOU DECIDE WHEN GETTING BACK TO THE FIRST DECK AND REFILL YOUR ENERGY.   
          
            AT THE END YOU'LL FIND A SUMMARY OF THE ACTIONS IN THE ORDER I MADE THEM TO FINISH THE GAME.
                    
THE SHIP IS DIVIDED IN 5 DECKS.

(As You know we have a serie of chambers divided by some "halls".ll
 Here these Halls will be identified as gh(great hall)(number 1 or 2)D(deck) number(1 up to 5)
(MAIUSC PHRASES ARE IMPORTANT READ IT:) actions are underscored with ---)


FIRST DECK :              _______                                    _______
                         |       |                                  |       |

START GAME(Of course you'll start on the first deck of the ship)  

                      

1)TAKE THE SWORD garded by two skeletons.(Room A)
  --------------

2)The bell in room B if hit with the sword will give You full energy.
 (You can do this any time you reach this room.DO IT WHEN YOUR ENERGY LEVEL
  GETS TO LOW.YES IT'S A BIT BORING GOING BACK EVERYTIME TO THIS ROOM TO REFILL ENERGY,
  BUT IT WORKS THIS WAY.ANYWAY THERE'ARE A COUPLE OF OBJECTS IN THE GAME(DOUBLONS)
  THAT GIVE YOU 100% ENERGY).

3)GO TO ROOM E. HERE YOU'LL SEE AN EMPTY ROOM WITH TWO MICES.
  YOU CAN MAKE THEM DISAPPEAR FOR A WHILE USING THE SWORD BUT HERE THERE'S
  AN IMPORTANT ITEM TO GET!!!.
  GO TO THE LEFT SIDE OF THE ROOM TOWARDS THE LOWER LEFT CORNER.YOU'LL NOTICE A SHELF
  WITH TWO SACKS ON IT AND AN OBJECT BETWEEN THEM(SEE '*' ABOVE)(AND TWO SACKS AND A BARREL BELOW THE SHELF)
  BRING YOUR PLAYER ASIDE THE SACKS BELOW AND WITH THE SWORD
  HIT THE ITEM BETWEEN THE TWO SACKS ABOVE THE SHELF.(you'll spend some time in finding the right position)
  YOU'LL SEE SOMETHING FALLING FROM THE SHELF AND YOU'LL GET A PIECE OF MAP!!!
  THE FIRST(AND EASIEST ONE)!                     ---------------------------
  --------------------------

3)Great hall1 deck 1(gh1d1) contains a oyster with A PEARL IGNORE FOR NOW.
                                                   -----------------------  
                 
4)Great hall2 deck 1(gh2d1) contains A BLACK FLAG IGNORE FOR NOW.
                                     ---------------------------

4)Entering Room D will make You fall on in the second deck  IN ROOM E OF SECOND DECK WHERE WOU'LL FIND THE POWDER
 (Up to You if choose this way or take the stairs in room C)-----------------------------------------------------         

5)Room C leads downstairs.(ROOM A DECK2)

6)GO TO THE SECOND DECK(use room C or D)
  ---------------------


SECOND DECK

1)gh2d2 contains a flashing skull.
  BE QUICK ENTER THIS HALL HIT SKULL WITH SWORD(YOU'LL GET IT -"yOU'VE FOUND A SKULL!"message will be displayed)
  AND GET OUT AS SOON AS YOU CAN.              -----------------------------------------------------------------
 (THIS ROOM IS TERRIBLY ENERGY CONSUMING!!!).
  In my opinion now it's better go upstairs(ROOM A) and refill energy!(let this one the first action
  you perform in this deck and then return after energy refilling)


2)Room C leads downstairs.

3)Room B contains a long chain with a flashing comb. IGNORE FOR NOW.
                                                     ---------------
 (get back here when you'll find the ANCHOR in deck 4
  to solve this piece of puzzel anyway here the way :
  FIND POWDER-->4 DECK ROOM A, TOUCH THE CannON IT WILL SHOT A BARREL,
  TAKE THE ANCHOR GET BACK HERE,HIT CHAIN WITH SWORD AND YOU'LL SEE THE ANCHOR PULLING DOWN THE CHAIN
  AND YOU'LL GET THE COMB)
                                                     
4)gh1d2 HERE ATTENTION!IMPORTANT ITEM HIDDEN.
  IF YOU ENTER FROM ROOM C SIDE GO TOWARDS THE OTHER EXIT DOOR.(IF YOU ENTER FROM OTHER DOOR SIMPLY STOP)
  IN FRONT OF IT(DOOR) STAND A CHEST ON THE LEFT AND A TABLE ON THE RIGHT.
  MOVE UP YOUR CHARACTER UNTIL IT GOES BETWEEN THEM AND TOUCH THE WALL,(SEE '*' ABOVE)
  THEN HIT THE WALL WITH SWORD. THE WALL WILL BREAK AND YOU'LL FIND A LARGE BELL!!
                                --------------------------------------------------

5)Room D leads downstairs.

6)Room E contains a little sack of powder(that will serve to activate the cannon in 4 deck)

  ----------------------------------

7)Room A leads upstairs to room C of first deck.
