According to tutorials, i tried entering the coordinates for cabin before I entered the coordinates for the white cube but I got nothing. Then I tried entering the coordinates after I got the cube but before I fished it out and nothing. I just don't understand itttt. FYI for all the players out there you do not need to play the whole cave game before getting access to the submarine. Just remember the pattern to enter into the door and it opens!!
