Looping Doors: SubwayLooping Doors: Subway

You are stuck in a loop in a subway station. And there are two buttons in front of you. You need to press the right button 20 times to get out of this loop. Memorize where the items are in the subway station in level 0. You need to find out if there are any anomalies in the next levels. If there are, press the red button, if not, press the green button. One mistake will send you back to level 0. Good luck...
