Re: Can't retract to go under TUNNEL?
 

Seems the GDC made the sensible clarification there. The way I read the rules, the intent was for us to be able to change in the Z axis direction to fit through the TUNNEL, but not expand outside our FRAME PERIMETER, except for a MECHANISM below the BUMPER ZONE which is allowed to expand up to the BUMPER PERIMETER for up to 2 seconds, and then must remain retracted for at least 2 seconds (I can't wait to see the ref's try to call this one.)
