I really enjoyed this. We also had a combination lock puzzle in our game and we are getting a fair few comments about not being able to figure out the combination. I have to say I like your clues. You had allusions to the answer and red herrings which made it fun and quite satisfying when I finally figured it out.
I also must agree with the comments regarding the axe. I think the use of the axe is clear enough the moment you get it. I think the lack of feedback when you actually use it is a little confusing, but since the path forward is linear enough, your trial and error will bring you to the solution.
Great work!
