ASCII and the Argonauts: Astral Plane

Far less known than its namesake from the same SpeedIF competition, this easy one-puzzle game may still prove a pleasant bite-sized diversion. The way the PC moves through the game world is of a particular interest; and "ASCII" of the title plays here a somewhat bigger role than in the game by J. Robinson Wheeler.

After figuring out how to win, for an additional challenge, try to win in as few moves as possible. I managed to find a solution in 42 moves; I wonder if there's a shorter one.
