I stopped when I had 50 food for the light and 50 food for the dark. The constant reminder that I was doing evil was killing me!! I really like your use of the basic shapes to come up with all of the graphics for the game. It was simple and I had to force myself to stop because my OCD could have kept me going forever to see if it would ever end or to see how high I could get that number for the food. Well done :)
