I think finding food should be more of a challenge and more fun, it does'nt add very much to the game the way it works today. My suggestion is to make wild animals we can hunt. Also i think we die to fast of starvation and dehydration, it takes more than an hour to starve to death irl:) Food should be more difficult to get, and when you eat, it should take longer time before you have to eat again. Also i think blood should regain over time, and not by eating..
