Currently in ktron there are walls surrounding the entire board. I think, as an option, it would be good if you could disable the walls. When the walls are disabled, if you past the edge of the board you end up at the same place at the opposite side. So if you go off the top, you end up at the same point at the bottom and vice versus. Similarly, if you go off the left you end up at the same point on the right and vice versus.

If you combine this with costum levels, people could design their levels with walls only in some places (although walls could still be disabled entirely), and in places where there are no walls the level wraps around.
