- Pack 8 leaves into 1 peat node.
- Leave peat nodes near soil and moisture to decompose further
into humus.
- Humus is a high-quality soil that works like dirt in most
ways, but grows trees quite a bit faster.
- Humus converts to dirt via grass (and eventually maybe other
plant cultivation activities).
- Leaves no longer decay into air.
- Leaves compost over longer time, following tree growth logic
(i.e. based on moisture and soil) when not exposed to air.
- Leaves left in the sun decay to nothing.
- Leaves deprived of air decay into dirt.
TODO:
- Decay out of stack nodes, half-life qty?
- Dig particle effects for node destruction; create API and
apply to other places?
