Somewhat getting close to being done, press space to advance a year, and every year you can click the name of an animal or plant and add or subtract 5 population (a to add and s to subtract). No objective yet so just try to have the food web not instantly collapse (keep berry bushes alive).
Everything works somewhat well, but I'm now trying change the code so animals will go after a population even if it's too small to eat, instead of just starving when there are no more berry bushes.
