Alien planet where raider flora terraforms your path network as it spreads; you grow counter-species towers whose roots compete for the same soil. Signature: seed a rival bloom on the terraform node to reverse the path change.
Magenta and cyan alien botany, twin moons, bioluminal spore drifts, black soil, strange pollen.
Click, Enter or Space to start. Place and upgrade towers with the mouse and number keys, or by tapping on touch, to stop each enemy wave before it reaches your goal. The HUD tracks lives, cash and wave.
