Condensing this walkthrough into something that doesn't have to be sifted. I ran into this section of the game by accident, and found it to be a real trainwreck. The walkthrough solution is just as convoluted, so here's the context-free solution.

From the beginning (where you can read the entire sign) :

Aron Doll : UP DOWN UP DOWN (note - you can keep or huck this thing, and the default is huck. If you huck it you'll find it again outside the maze)

Ice Crest : RIGHT DOWN UP DOWN

Getting the hell out : DOWN RIGHT UP LEFT then LEFT DOWN UP DOWN then any direction.
