Okay, so from all I've heard, there's a small life crest in dun webb. I can not find it. I looked at the (only) walkthrough I can find and all it says is "It's in the same place as puzzle piece 13" Which is beyond the green door in the mine shaft. I've played 2 copies of this game so far, and the only thing beyond the green door is one switch, and a ladder up the wall to a black chest containing said puzzle piece. behind it is a kick-over wall that lets you into the purple door area. That's it. nothing else. So if someone could give me a more detailed description of where and how to find said life crest, I'd appreciate it.
