Good atmosphere and graphics/sound. One piece of advice: for a game jam game, you might want to make the build a little quicker. In this format, as people are attempting to try out a lot of peoples games, we can lose patience quickly and can start wondering "what's the point / punch-line of this game and how it fits into the theme". That said, as a stand-alone game, I bet this could be pretty cool. Nice job on making a very comprehensive game.
