green can walk with the w s a d buttons... and red with the arrows! agree on wich mode you wil do! do you go for who gets the most poinst within a time [you have set the time bij yourself...] or do you go for the most points until the other one is finished? [ there are already in the game so you get points if you walk...] or are you just going to compete against each and try to kill to kill the each other?
