Guide your CromoZome to eat food and other CromoZomes. There is a balancing element between the CromoZomes, and as you eat your CromoZome grows and gets stronger. Get strong enough and you produce another CromoZome based on your strongest traits. You then play with this new CromoZome. Eating a blue CromoZome increases your speed, eating a red CromoZome gives you double energy points than normal but slows your speed and eating green loses you one health(poison) but you gain a green segment and this could poison another creature. You get a bonus for eating the same food/enemy segments as your starting colour.
