Left-drag from a colony: to empty space = eject, to a node = grow hypha (flows start → end) Left-click a hypha = reverse its flow · Right-click a hypha / wall = cut / remove Right-drag from a colony = build wall (stem and crossbar block lines) Right-drag empty space / WASD = pan · Wheel = zoom · R = new round
Feed a gold boost to capture it · 1 / 2 = Sever / Flow while you hold them
