This whole challenge is weird. If I understand it correctly, he could just hang around the entrance area of each floor and technically survive till the time limit expires? I mean, he'd never do that of course, and that would only work till a challenger hit a stage where the entrance area wasn't safe, but it still feels a bit odd to me. If someone doesn't strengthen themselves in the little time they have on each floor, wouldn't they just die when it speedruns them through all the floors?
