Taproot

Grow a root as deep as you can.

Steer left and right as your root pushes downward. Rock kills you

on contact, and your water is always running out — so you have to

reach for the pockets buried in the stone.

Side niches hold nutrients, but they cost you: no water in there,

and the walls come close. Collect enough and you unlock new root

colours.

The deeper you go, the faster you grow and the tighter the passages

get. Every run ends in the same place: you got greedy, or you got

thirsty.
