Worm Sizes and Colors

I made it so worm children take on attributes at least as strong as the weakest parent (plus some random chance at becoming stronger). Size increases as worms get larger, and the color tints greener as they get speedier. Once 75 or more worms exist (I might change this count later), an overpopulation situation occurs and no more mating happens until the death tool is used to weed out the gene pool. Screenshot:
