Currently ktron has 3 modes: tron human vs. computer, tron human vs. human, and snake human vs. nothing (just eat). I think there should be two additional modes: snake human vs. computer and snake human vs. human. These have two snakes, both growing by eating and, like in the tron mode, running into the side of another snake kills your snake.

I can see two ways this sort of game would be played. One, the objective is to kill the other snake but you can only grow by eating dots. Second, the objective is to eat a certain number of dots, and if you die your apples get set back to zero (and your snake shrinks to a small size) but you come back to life immediately and the game continues on until one side has gotten enough dots.
