Expanding on "scent".

OK so basically meat creates scent in this game. (that includes when you're bleeding; we are meat, too!) All good.

 

Thought: when you are trying to survive like in this game, something else happens: we get smelly. Dirty. Foul. Yucky. Lack of cleanliness always leads to scent. I wonder if that could factor in. (perhaps only for higher difficulties) And to counter it, we'd need to clean ourselves once in a while. 2 ways:

• water: stand under a waterfall then dry off before freezing, this already happens in a few places, and/or, fill a tub with heated water (more difficult to implement though)
• smudge fire: using certain fuels in a fire to generate a large amount of smoke, which masks scent. (could use things like tinder plugs (cedar), cat tails, birch bark, old man's beard) Just add to a fire, wait for an hour or whatever, voila. Only works in enclosed spaces using a camp fire.

I thought of one more option: We might even wipe ourselves with a damp cloth.
