Board notes 5 details

Layout: Boxy starts at the left pink door beneath the prompt "Follow the rules... again?" A right-pointing finish arrow and a suspended square signal lead across the scrolling ground to a distant door.
Goal: Survive the red-light cycle, break the hanging rule controller, and continue to the far-right exit after it crashes.
Opening: Hold right on the glowing green face and release the control as soon as the signal darkens or turns red.
Danger Zone: Any movement during red resets the run, but merely waiting through every cycle never removes the final restriction.
Mechanics: Stop-and-go traffic timing is combined with direct scene manipulation; the suspended signal can be tapped loose from its cable.
