📖 How recipes work
Every plant starts as the letter A. Each time it rains, every capital letter is swapped for its rule. The small letters tell the pen what to draw:
f | go forward, drawing a line |
b | go backward, drawing a line |
l r | turn left / right a little |
+ - | bigger / smaller steps |
[ ] | start a branch / hop back to where it started |
g | green pen (leafy, bendy) |
w | wood pen (brown, strong) |
y | a yellow flower here (bees love these) |
p | a pink flower here (butterflies love these) |
Plants fall over if their lines cross, if a green stem holds up too much (wood holds far more, but not everything), or if they grow down into the dirt.
Green catches sunlight, but only what reaches it: every green bit above it takes half, and wood blocks the light completely. Wood and flowers cost energy every tick. A plant that runs out of energy starves.
The field has two climates, left and right, each with its own rain and sun. Rain soaks the soil and sun dries it (the dirt colour and the % show how wet it is). Green and flowers are thirsty, wood hardly at all. A plant in soil drier than it needs loses energy fast.
