Excellent game
Just a few "technical" issues - the wolf's head you mentioned :) Finding some items felt pretty much like pixel-hunting, too. Maybe I got confused because I did click around those areas earlier and found nothing, so I didn't expect to find anything later - although I think this is better than walking around with a bunch of stuff I don't know what's the use for. Maybe they just should be easier to see.
Also, the text boxes opening whenever I click an inventory item were a bit irritating because I had to close them explicitly. An "examine" icon or button might have been better.
Other than that, I loved the game! Graphics, story, the occasional joke... I don't even need to await a sequel b/c I'm going to play it right now :)
