have to do something no sokoban player does in the upper left hand
corner. Also, the antitanks in the upper right hand corner are decoys
and can be ignored. Hope that helps. For 417"the 5th corner" you come
in through the top, you don"t need one of the blocks up there, but you
do need an antitank. The "unforgiving" is another of my favorites, but
coming up with a clue isn't easy for this one. There is also a
"Unforgiving Too" in the level file that is almost identical. As for
level 679 [another great level] you need the mirror on the right. As
for the Kheper levels, can't help you there!!!
