I think that there should be an option to play "Hard Core mode" on mine craft. In Hard Core Mode you would need to feed, rest, and give water to your block person when he needs it. The feeding drinking and sleeping times would all be shown 3 different meters on the left side of the screen. If your player doesn't get the food water and sleep that he needs he will die. Please tell me if you like the idea and if anyone asks for more details i will add them
