This is so cool! I love that you were able to make a whole sandbox minecraft-like game in just the span of a jam! The hygiene mechanic is a really cool concept (I love that original Tumblr post that this comes from) and implemented as a well-thought-out mechanic. (By the way just so you know hitting back in the options menu crashes the game on Windows. It's impressive that you have settings at all, though!) It would be nice if there was a way to keep track of your hygiene other than zombie aggression, the particles, and how green the screen gets, but I also get if keeping it ambiguous is part of the mechanic. I would also recommend adding an unbreakable layer to the bottom of the world to prevent people from falling out. (Doing that crashes the game btw). In any case, amazing job with this!! You somehow managed procedural generation and crafting among other mechanics in the time of a game jam!
