A very good game, especially since it was made under time pressure.
Unfortunately, it largely depends on luck. The only time I won, I had two pieces of meat every night and used them both to save myself and the guard.
Without them, there's a little to no tactics involved. Once the werewolf starts chasing you, you've lost. He's too smart to be slowed down by buildings, too persistent to change targets. On the other hand, you get exhausted too quickly and even all your stamina can't be used to outrun the werewolf completely, just to prolong the chase. There's also no place to hide during the night (e.g. jumping into a haystack) and the guard is defenceless against the attack (it'd be cool if you could reliably save the guard by pelting the werewolf with a stone and making him chase you) and unlike you, he wanders about randomly, so letting him stumble upon the werewolf is an instant game over (and luring the werewolf away without a piece of meat, too).
All in all, I think the difficulty still needs a little balancing, especially the amount and regeneration of stamina, and your running speed. Basically, any feature which gives you a little edge over the werewolf and depends on your skill, not a randomly appearing consumable item.
And now that you have time, I'd change the ending pop-up. It took some effort to earn the ending! Show them hugging or something, don't just write 'Game Over' as if you lost. :P
