That was REALLY fun. But WAY too easy. I made it to 100 million without any problems. You need to make the high level stuff WAY harder, maybe add burrowing mines and stuff that will hurt you underground. Also, adding a camera scaling option, like the one in Spore, would help make the game easier to play. My worm got pretty big at the end, and it was hard to see where anything was.
