$\}$ makeMove needs to return true if the game has been won and false every time it's not won, the move is not asked for here but instead provided as a parameter, interpret the user's input from q to quit, l to left, u to up$,$ d to down, and r to right. If it is q then quit the game, elsewise check if the move is valid using the method and update the player position, once done mark the new cell as visited.
