The object of the game is thus :

    The game prints out five evenly spaced arrows in the centre of the screen.
    The idea is that the player has up to DELAY seconds to use their left or
    right arrow key depending on the direction the middle arrow is facing. Uses
    non-blocking I/O and if after DELAY seconds there is still no input the
    game will proceed; in this case the score stays the same but the loops
    counter is increased (ironically decreasing the total score at the end! :).
    Hit 'q' to quit the game at which point your score (out of total loops)
    will be printed along with the percentage you got correct.

After compiling the game (see COMPILING file) you can run the game like:

    $ ./arrows

In the COMPILING file I discuss how to change the number of seconds.

To quit the game just hit 'q'.
