Hey there, new speedrunner from the Netherlands here, looking to grind myself some WRs :). I was reading the rules on IL runs ( https://www.speedrun.com/st/The_journey_begins#0.6.x to be precise), and wondered about this one:

"Some levels require you to show the black screen at the beginning before finishing a level. Those will be stated."

and further on:

"Some levels require you to show the black screen at the beginning and at the end."

What black screens are meant here, and which levels do these rules apply to?
