In this play, you will go the blows using keys I, O and P, and you will move thanks to the numeric keypad of your computer (portables to abstain from, therefore). You incarnate a ninja which must (oh, as it is original) clean up the various enemies with the screen, knowing that they have a minimum of intelligence, and that they will jump you above as soon as you venture too much close to their territory? What is to be noted, in this play, in fact graphics originals do not use (for most of the time) only two colors.
