QUBE RUSH

Waves of qubes roll toward the edge. Stand on a tile and press SPACE to arm a trap, then press SPACE again when a qube is on it to capture.
GREY qubes must be captured — each one that falls off destroys a row of the stage.
BLACK qubes are forbidden — never capture them, let them roll off.
GREEN qubes leave a 3×3 advantage zone when captured — press E to detonate it.
Don't get rolled over. Don't run out of stage. Clear all 8 waves.
