If hunger is greater than 20 or if fatness is greater than 35 your monkey dies(right now, the program just stops if he dies. I will add an animation). Every once in a while you get money. Spend it on food for your monkey. If you feed him a lot he gets fatter. The fatter he is, the hungrier he gets, so don't overfeed him. Soon, I will make it so you have to clean him, play with him, clean his waste, and other annoying things. :)
