Stop sign.

After the second input has been received, the door into the chamber split into two automatically, letting Jen inside. The chamber was rather spacey and mostly white, yet still much smaller than the first hall. The floor consisted of soft-ish blocks with a side of 6 to 7 feet that simulated uneven terrain and had many different grips sticking out all over the place.

"With the right equipment, it must be fairly easy to replace these blocks with... other blocks."

*SNAP*

It took one to snap Jen into full focus on the target. The signal was fairly late, so the key must have been deep in there. The girl ran towards the center just to cut some distance, so she could be closer to the key, no matter how quick she would be able to spot it. As she neared the center of the chamber, the lights went brighter, and an upward pulling **** introduced itself to Jen's belt. At first, it was weak, but it was growing alarmingly strong.

"Now I get why those grips are all over here." — before she was **** by the **** of magnetic attraction, Jen grabbed two of them grips on the floor firmly and securely. It was not hard to hold on... at first. However, the field was just not ending. In theory, it was possible to travel by gripping forward, but it was way too risky. One slip was enough to nullify everything that she managed to go through. — "Please, end, just end."

Just when her palms were getting dangerously sweaty, and her well-fit arms were losing muscular potency, the magnets let her go. It was a great relief, she took her time with putting her muscles at ease while she strolled deeper into the chamber.

Then she stopped. Her belt would not go further. And no matter how hard Jen looked or touched, she could not locate anything alien holding it. When she lifted her feet away from the ground, putting all her humble weight on the belt, it remained airborne, descending ever so slowly, no more than a quarter of an inch per second.

Once she was low enough to grab the floor grips, the girl was able to pull herself forward quicker, although it required using her upper limb power again. Up and down the artificial terrain, she kept going where the snaps were leading her, wondering what was going to happen once this field expired as well?

It did expire well before she arrived at the key rack hiding in plain sight, but on the opposite side of the white hillclimbs. Jen picked up the key, opened the belt and watched it fall to the floor, leaving marks on her waist that were way less severe than she would have expected. In the meanwhile, the ceiling lights dimmed down even more. The exits closed down, and Jen was stuck inside the empty kid zone, locked up for the night.

"Well, fuck. Not like I was any close to making it in time, though. Guess I, uh, wait for some new contestant to enter the box."
