"We managed to fix the arrows, but now you need to do something about it..." Press an arrow key to move one space in that direction. Holding Z while pressing the arrow will allow you to move two spaces in that direction. Do not cross any of the walls in the maze. You cannot make the same move twice in a row. Doing so will NOT cause a strike, but you will not move from your current position. The number in the center is the amount of moves you have to reach the end, identified by the green in the bottom-left corner. If you run out of moves, or get to the green prematurely, you will have to restart from the beginning. Get into the green with exactly that many moves shown to solve this.
