Ghosts, level 7

START POSITION – Take the missiles. Then go through the door behind you. Open the secret door.

Open the door to the room with the ghost. Back away and have it follow you. Then rush past it into the room and get the axe in the little corridor. Deal with the ghost.

Fight the enemies in this area for a missile launcher and a 1-up.

The best choice now is to go back to the room where you started. Open the door ahead and start the action. Clean out the northern section of the floor.

Clear this room. You find a 1-up behind the secret door, but leave it if you don't need it at present.

Find a revolver behind this secret door...

...and more missiles behind this.

Make it to this point. Be prepared for surprise attacks. Open the door to the east. Try to kill the pirates ahead by blowing up the barrels.

Go through the central room to the south and make it to this point. Find the brass key and a 1-up beyond the secret door.

Open this secret door, you need to step on a poison puddle to do so. Move through another poison puddle and reinforce with the two health chalices ahead.

IMPORTANT! Do NOT open this secret door before you have both the brass key AND the iron key. Otherwise you will get stuck!

You may all the same choose to venture into that area at this point. Break the mirror and finish with the ghosts. You will get a glimpse of the captured girl. Beware the purple monsters in the niches!

The silver key is hidden behind the two barrels in this room. Blow the barrels up. The moment you do that the Skull Boss will come after you from the cell he is in. Don't let him surprise you!
Get the silver key in time (even if you have to rush through the poison puddle), then run westward steering clear of the death chalice in the middle of the hallway.

Tour the floor all the way here for the bronze key, be on the look-out for the Skull Boss.

With the bronze key you can tour the whole floor both ways making it easier to avoid being cornered by the Skull Boss.

Engage in a dangerous game of hide and seek with the Skull Boss. Find extra missiles and plasma ammo in the southern rooms. Pick up a 1-up in the Skull Boss cell, and other 1-ups you may have left behind.

Finally defeated the Skull Boss will leave you the iron key, and 3 x poison! Be sure you end up with more than 60% of health (more than 80% if he falls on an existing poison puddle) before taking the iron key!
Avoid having him fall on a bomb or a death chalice!

Save the girl in this room. Go east through the secret door.

Continue east through another secret door and reenter the hallway. Enter the cell immediately to the south and open the next secret door. Blow up the barrel and have two armours come at you. Deal with them.
Retrace your steps and open the secret door in the plank wall. Take the cross and the death chalice. Continue south.

Open the first of the next two secret doors. Bring down the armour, take the cross, open the second secret door, take the gold key. Don't go through the door, there's a bomb right outside it. Retrace your steps.

Take the death chalice and enter this room. Deal with the ghost if it's still there. Take the cross.

Take this death chalice for full treasure quota.

Exit the floor at this point.
