Liked the concept, not enough to carry it on
Preloader was annoying, the the red and gray lines moving at high speed were a sight for sore eyes.
The music had no mute ability, that brings you down
The graphics were cute :D
Your ideas were original, but the gameplay was too repetive, maybe allow you to select difficultly levels, and use less card numbers so war is declared more often?
little interactivity, press button, press button really fast...maybe a bar showing your button progress in comparison to the computers
and Violence was okay, driving a sword through the poor mans head :P
