I did not solve this kata but I did some trials and it seems very clear: You have a 2d grid of code, move down means the pointer shifts to the next line, up to the previous, etc.

You can have a look at this kata and see similar pointer movements.

What on earth do the directions mean, here?

Start moving right.
< Start moving left.
^ Start moving up.
v Start moving down.
? Start moving in a random cardinal direction.

What is moving in a direction? Is this supposed to simulate instruction pointer movement? Surely not. How exactly does an IP move "down"?

Jeez. This was a kata that really underlined the importance of Linq statements.

Wow this is an elegant solution. Good work.
