- Health, stamina, hunger, warmth and wet with HUD bars, status tags and clock - 20-minute day/night cycle with moon, stars and lit clouds - Campfire fuel (2 min start, 15 min max), heat radius, cooking needs a lit fire - Berry bushes (regrow 10 min), mushrooms, roasted mushroom, torch - Stamina costs for sprint, jump and harvest hits - Death respawns at island start and leaves a grave bag - Saves include stats, time of day, fire fuel, regrowth timers and graves - New test_survival_stats suite; tests fail if a script error aborts them
