That was bullstuff.
Night was falling, I had traps set up around my base, and I was swarmed by I'd guess 6-8 regular and ice hounds. Could have fought them off during the day and during the summer, but the amount coupled with the fact I had to stay somewhere near my base lead to my death on Day 60.
Next game, I'm turning off lessening wolves, it's not really a survival game without an environment that you can learn from, not one that exponentially gets harder with your fortune.
