Warmth, food, water and energy as bars of 0..100; what an hour of doing something costs them (the package's rates: a full bar is a day at a trip's median); the countdown when one runs out, reported as NEEDS_CRITICAL / NEEDS_RESTORED / NEEDS_COLLAPSED facts. The body's work, the air, clothing, the sun, the difficulty and the effects come through the NeedsWorld port. Its own save section. Uses ludic_base only; 13 tests.
