nice "coldy / glassy" music, great execution to make it feel actually "wintery".
I think it's really hard for me to make puzzle games that actually make sense, and I think this one does make sense, so congratulations, I have much respect for that.
Also I like the simplicity of the art. really few colors and small drawings very well executed. less is more, congrats!
said this I would suggest, I bit more of a "difficulty curve", I explain: I think you have cool concepts like the hermit thing or the merchant, and the this -1 food +2wood, +3turns, it's really clever truly, but in my totally subjective thing opinion this elements could have been introduced way earlier.
appart from this I think it's a very polished and complete game. congrats!
