Once you've gotten the code to open the metal door with the wine crate next to it, I recommend saving the game here. Next go down to the "tube", where you need to press the lift button to get the lift down. Before pressing the button, make sure you are not in the lift but outside of the tube, like shown in the picture.


Once the lift has went down, try to position yourself well, and try to fall on the edge of the lift so you don't fall to the ship's "basement" and the game ends (this is why I recommend saving the game, so if you fall you don't need to start fully all over again) Once you've fell to the lift's edge or the so called "barrier", aim to the ship like I do in the following picture.


Now that you are aiming to the point in the picture, walk forward to fall to the ship's deck. On the deck, turn 180 degrees to the ship's cockpit. Go to the left side of it when viewed from your perspective as I am in the picture.


Start walking forward's to the end of the ship, but make sure you don't fall from the edge of the ship since the barriers don't have a collision.


When in the rear of the ship, just walk to the almost exact point where the ship ends and walk thru it. There will be a spotlight. Just start walking towards the spotlight. When you turn 90 degrees to your right, you will see a staircase leading in to the cave's wall. Start climbing them.



Once you have walked thru the cave's wall, it should look pretty much like this:


Continue climbing until you get here:


Then walk on the edge of the tiled platform. Once the platform ends, there will be black platforms, which are pretty hard to see. To make it easier to see them, I recommend turning your screen brightness up a bit if you can. The platforms have also been highlighted in the next photos, so just follow them.




In here, turn 180 degrees, so you will face a completely black wall!


Here I turned 180 degrees and face the black wall

Just continue to walk straight in to the black wall, where you the will walk thru it, since it has no collision set. That's where the secret room is. The following picture is the room, so if you want to see it yourself for the first time and not through a photo, don't look at it!
