The game starts with the trapper's turn, to control it you have to use E (goes up to the left), R (goes up to the right), F (goes right), C (goes down to the right), X (goes down to the left), S (goes left), and then the trapper has to click on ONE tile to close it. If the cat escapes the board, it wins, if it steps on a closed (dark green tile) the trapper wins.
