Manage food, wood, and warmth to survive three different cold spells, each lasting 12 days. Read the forecast for tonight and the following two nights before choosing what to gather or how to improve your heating.
Choose a job with WASD, then press RETURN to spend the day on it. Gathering wood or food adds 7. FIRE spends 3 wood for 9 warmth. WALL spends 4 wood to raise insulation by one level, up to two levels.
Directions work on the keyboard or pad; the pad button also acts as RETURN. SPACE opens confirmation to restart this stage. NO is selected initially. Choose with A/D, confirm with RETURN, or cancel with SPACE. Play pauses during confirmation. CTRL+C returns to BASIC.
Food, wood, fire, and walls have distinct graphics. The chosen job's supplies move toward the hearth. Flickering fire and snow accompany the scene; work, eating, and heat loss resolve separately with sounds and short pauses. Wait until the sequence finishes before pressing again.
Each night consumes 2 food and warmth equal to the forecast cold minus insulation. Insufficient food or zero warmth causes failure. Food and wood each cap at 30; warmth caps at 24.
