Not bad.
Still,i don't really like the way you used chess as a game,though.Not all the pieces were used,and it seems pretty stupid just using that dumb knight-no bishops?Rooks?More enemy knights?No back-up?No king?No queen?Er,not even some back-up pawns?No calvary for the invasion?Just pawns,pawns,and more rampaging pawns???!Well,yes :P.Although i wouldn't agree with the "Chess comes to life" phrase you said in your comments,lol.Not with only a knight and pawns!Still,i might misunderstand-I only saw pawns,though.
