If you get hungry - and you will, quite often - there's over 50 unique food items on the island of Malayalam to eat. Mushrooms, anyone?
The thing with mushrooms is that you need to know which of them are poisonous and which can be eaten. Also generally every food item has a dynamic nutritional value, which means that their healthiness varies. The player can view a "menu" to see what sort food is most useful at that time.
