There were only a few ways to exit the Tower.
The first was simple: refusing to ascend.
Whenever a challenger cleared a floor, a system notification would appear, calmly asking whether they wished to proceed to the next.
It wasn't aggressive. It didn't rush. There was no countdown, no pressure—just a quiet prompt, waiting for a response.
If the challenger declined, the Tower didn't immediately throw them out. Instead, it asked a second question: would they like to continue to the next level?
It was a different thing entirely.
A level, unlike a floor, didn't always mean a drastic shift in challenge—it could be a side path, a different kind of trial, a detour from the main climb.
But still, the Tower gave them the choice.
