Terminal mode controls

• You are Player 1. Your objective is to move your red pawn from the top of the board to the bottom of the board
• Player 2 starts at the bottom and is attempting to reach the top of the board
• On each turn you can either move your pawn or add one fence piece to the board (you have 10 to start with)

Moving a pawn

• Use the cursor keys to choose where to move to. Your pawn may only move one square on each turn and cannot move diagonally
• The "[ ]" mark where your pawn will move and is coloured green for a valid move and red for invalid
• Once you have selected a move, press enter to move the pawn

Adding a fence

• Press tab to switch from pawn to fence mode
• Use the cursor keys to choose where to add the fence
• Fences must not cross other fences, or completely block either player from reaching their goal. An invalid fence position will be shown in red
• To rotate the fence, press space
• Once you have positioned the fence, press enter to place it
