Custom Snakes

Snakes


Smart Viking
(smartviking)
A game of snakes, designed in such a way that it can be played in many different ways, you can change the size of the window, the size of the snake and fruit, the speed of the game, and how nutritious the fruit is.

To see how to change these things, run:
$ python custom_snakes.py help

Not tested on Mac or Windows, please tell me whether the game works on those systems.

    Terribly coded, my infant cousin can make a better game out of sticks, you may as well quit and just go back to McDonalds.

    it's works fine on Windows Vista!

    that just looks like you copied wormy and tampered with it.That really isn't a big deal, unless you created it without looking at any answers, or even knowing what the  game was.
    Anyway, it's not very smart to make similar games and post them on the web.
