Snakes and Circles

Snakes and Circles is a free-avoider game. You are a snake made out of an infinite series of glowing orbs. Your only goal in life is to feast upon circles of light that are the same color as you, it sounds easy but as you slither through life you will encounter horizontal beams of light which will alter your very being. As you pass through the horizontal beams of light you will take on their color. In doing so this means that you will change colors and thus be forced to consume the glowing circles of that new color.
