I've finished the map for Maze "B" (levels 2, 6, 10, 14, etc.), and I also modified the map for Maze "A" a little bit to be more accurate. Specifically, I noticed that the monsters' lairs extend back one more square-- that is, they're two squares "deep," but you have to fight a monster and can collect the treasure in the first square. And some of the "dead ends" are really more like niches, because if you go "into" the so-called "dead end" and do a U-turn, you'll see that you didn't really go "into" a new square at all. For example, if you're in an intersection facing what appears to be a dead end, and move "forward," the "side exits" disappear; but if you then do a U-turn, you'll find that you're still in the intersection. So I changed those "niches" from full "dead end" squares to just orange "half squares." And finally, the screen turns red for the "down staircase" two full squares before the actual staircase, so I colored three squares red-- the two squares before the staircase, then the actual square containing the staircase, which is the square I put a "D" in. In both the up staircase and down staircase, you can't really go "into" the staircase square per se, because when you move "into" that square, you are taken up or down a level. I'm posting the maps in this thread, since this is the thread that has "maps" in the subject line!
