Yeah, I played as the pigs and brought down the Wolf's reputation to 0%. Then the next event would have sent him into the negatives, but it wouldn't let me, and even then the game still continued! I guess there is a minimum number of turns or something before the game ends.

Yea, each play spans seven days, one turn for the Wolf and one turn for the Pigs per day.
