Game rule:

    When the game starts, two pictures which
are almost the same are showed in the two
sides of the window. What you need to do is
to point out the five differences of the two
pictures by your mouse.After finding out
them, the next pictures are showed.
    The game has time limit. When the time is
over, your energy get less and less. You can
also choose to give up and go to the next
pictures, but the energy will still decrease
a bit. If the energy is over, the game ends.
    The way to calculate your score is that,
every time you find out one difference, your
score are added by the same with the remaining
seconds.

    Enjoy it !
