Skill
Energy
Energy and feeding rules across reviewed Duck Life games.
Overview
Energy is separate from racing speed skills. In 
Duck Life 1, feeding increases energy so the duck can keep going during races.
Duck Life 1
See 
Energy for the first game’s energy rules. Seed and 
Skill Seed compare the food effects.
Duck Life 2
See 
Energy for 
Duck Life 2. Normal seeds add 0.6 energy levels and Super Seeds add 3; both original Flash and later editions use those amounts.
Duck Life 3
The third game uses food-raised energy for race endurance, separately from its four racing skills. Energy caps differ between editions. See 
Energy.
Duck Life 4 Classic
See Energy for checked Classic rules and labelled original Flash differences. Feeding raises energy; the final level-150 racing-skill gate excludes it.
Remastered and mobile
See Energy for the redesigned Unity/mobile rules in 
Duck Life 4 Remastered.
Duck Life: Space
The source-checked reference Energy covers Space’s separate controls, training and progression. The creator confirms caps of 20, 40, 60, 80 and 100 through the first five worlds. Exact boundary display and older-edition differences remain separate checks.
Duck Life 8: Adventure
Adventure’s Health determines starting race energy, and Endurance slows its depletion. Boosting spends energy; consumable race items can restore it. Energy is not a ninth separately trained skill.
Duck Life 9: The Flock
Energy is developed by feeding, with limits tied to Cooking Pot upgrades; race energy also powers abilities. See Energy.
