Dave_Lemonade had it right when he called it “claustrophobic”; there’s this constant feeling of the situation pressing in on you. It’s very unforgiving… maybe a little bit too much so for my tastes. It seems like you absolutely have to drop what you’re doing when you get a warning, or else. But maybe that’s just because I kept pushing it too much. Perhaps some sort of meter or countdown to indicate just how close you are to dropping dead of hunger/cold?
One little niggle: requiring two different tools to harvest the plants just seemed like extra steps for extra steps’ sake.
