I am having a big problem solving the Skull Light puzzle in part one where, if the puzzle is solved correctly you get the Large Wind up Key so you can travel in the boat. I have tried numerous times to solve this puzzle with absolutely no luck at all. Could someone give me a few tips that would help, I would appreciate it very much. Thank you.

Just a FYI, if you don't get any answers, you probably should post this on the subforum dedicated for the game:

On the front page of the forums located here:

You'll see a list of the game subforums along the left hand side. There's a search box there as well.

As to your question, I see a fair number of walkthrus and discussions. Have you checked them out?

Hope this helps

I have a walkthrough and even though I have followed it and tried to solve this one, I have not been successful as yet. There are videos but they go so fast on this one it's hard to follow but I will keep trying. Thanks for the information. I appreciate it very much and will try it as well.

Just a tip - if they are Youtube video's there should be a speed control that allows you to select 0.25x, 0.5x, 0.75x, Normal (1.0x), 1.25x, 1.5x and 2.0x speed. Just click the thing that looks like a cog or wheel, then "Speed", then whatever option should be visible:-

Edit: Alternatively SHIFT < or > (the keys with , or . on them) also increases / decreases speed (and SPACE pauses).

Thanks for the info I think slowing the video down will help alot in solving this very hard puzzle.

Success! I have solved this very difficult puzzle partly by slowing down the video and partly by my own calculations. Thanks for all your info, it really helped!
