Lucika, you're totally right. I mean, the last update was on 7/31/2008! It even still says that kongai isn't illegible for the contest of 2 months ago!
the chance you get a card when you win depends on how many cards you've already got. so it doesn't depend on lvl or amount of players or something like that.
the attack power is random, sometimes an enemy keeps kicking you, and swordsman can hit you from a distance you can't hit them. the idea of the game is good though
