WESN

WESN (west, east, south, north) is the name given to the following principle:

"Whenever any object has a choice between moving in some or all of the cardinal directions, preference is first given to west, then east, then south, then north." WESN takes effect in the following two scenarios in GOP:


 * When an orb wants to move diagonally but there is a rock in the immediate square in that diagonal direction, the orb has a choice of moving in either of two directions around the rock. WESN tells the orb which direction to move first.
 * When the player is on top of an orb and clicks the orb, the player will first try to move one square west before attracting or repelling it. if the space one square west is blocked, then the player will try to move east instead, and if that fails, then south, and finally north.
