Challenges

Besides the game course achievements, the gamer can live acording to self imposed limitations or goals that bring extra difficulty. These limitations can follow some imaginative scenario or some other arbitrary, fun or ridiculous ideas.

Some examples:
 * You are a kung-fu aprentice in your way to enlightment. You only need your fists and feet to fight opponents. You don't use any weapons.
 * Live as hippie and never eat meat or kill the furry friendly bears and other friends of nature
 * Live as level 5 vegan, you never eat (or kill) anything that casts a shadow, that includes trees. Do raspberries have a shadow?
 * Some people do eat roadkill and enjoy it. Only feed on badgers, squirrels and rats.
 * Become Magellan on a raft, travel back and forth on the ocean.
 * Living as a dog, without tools, no clothes, no trading, no climbing and afraid of humans.
 * Only walking in one direction for the whole game, not turning arround or going backwards no matter what.
 * You are an caveman just unfreeze. Find a cave, the club is your only tool. Hit women on their heads.
 * Man are not welcomed to the new feminist world order. Found the feminist utopia, build a cottage and hire woman to follow you.
 * Children live in such a innocent world. Try playing with them. Throw things at each other, build rock castles, play with staffs as if they were swords.
 * The spirits gave you a vision, if you walk only backwords and always turn your back (literally) to your enemies, even if you die the spirits will give you the secret to Finish heaven.
 * You are Bear Grylls, you have your camera and your tools. Go someplace isolated and live without any human contact so everyone else knows you are harcore.
 * Axes are evil. Knifes are sharp. Abolish the axe dictatorship and never use them. Try knifes instead.
 * Fire shines, Set everything you can on fire. Make huge bonfires, maybe arround villages full of logs.
