I really like the artstyle, and the atmosphere that it gives, really enjoyed exploring (I think I exhausted the map). Some funny writing in there as well. I think the fact that furnace is sitting in the corner of the map does unfortunately make exploration more cumbersome as you have to go back a lot especially if you expand the map. But I am sure this can be solved with some smart game-design ;).
I digged it a lot, nice work!
