Orkuncakilkaya cf42214974 ludic.needs: a body's four needs, their rates, meals and the countdown to a collapse as a fact
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.
