AI moves draw energy.
You start with 600 energy, enough to grow your first world and forge your first document.
Energy never expires, and it is refunded if an action fails, so you only pay for what you receive. Buy more only when you want a bigger transformation.
Raise the river
Four packs, one river.
Every pack feeds the same river, and bigger packs stretch each dollar further.

A note on energy. No loot boxes, no streaks, no pressure to spend. Energy is here to grow your ideas, not to keep you clicking. You only pay for what you receive, and the reward is what you build, not what you buy.
