So, some of you may have already heard of this game before, as it was among the games that inspired H&H. Anyway, it's the most detailed simulation of slowly starving to death while hunting squirrels I've ever seen. You can also follow tracks of large game for days only to have it run away with your precious arrows in it, never to be seen again. In short, it's a fairly realistic and sadistic wilderness survival sim. Fortunately, there's also easy mode to feed yourself - cannibalism. People have a lot of meat in them, and they're not as skittish as the animals so hunting them is a lot easier. But real men hunt squirrels because it's no fun if there's no challenge in getting sufficient food.
Anyway, I'm bringing this up because the game has recently switched to donation-based, whereas before you had to buy it to play beyond 10 game days. So if wilderness survival sims are your thing and you don't care much for graphics, you can check it out here.
