Quality Control: Buttons

Welcome to Aperture Science's Quality Control Testing Initiative. Today, you'll be testing our Heavy Duty Super-colliding Super-buttons. Who's ready to do some quality checking? Update 1: Added a pedestal button to the laser relay that temporarily turns it off, and removed ceiling portalable walls from the second redirection cube's room, to prevent portal bumping. Update 2: Removed portalable surface under funnel room's hole to prevent shortcutting.
