If you take a look at the Dungeon Entrance video, you'll see that Kenneth designs the grid as a list of 2-tuples where the first value is the X co-ordinate and the second value is the Y co-ordinate.
(-1, 0) could represent left because the first value would be a negative movement along the x-axis (left) and the second value represents no movement on the y-axis.
imo, while I understand the coords he's using I think it would be simpler to just make the cords in a different fashion and have the tuples be a single number so you'd line them up like "column 1, row 5" etc.
