this 10 minute looks like 30min.
i don't understand what he meant with the time on the floor is different or smth
Basically, inside the waiting room (the safe village they stay), time flows differently than in the tower (as it's actual gameplay)
It means nothing for them, except that they have more time to train and prepare in the waiting room before going in the tower (it was roughly explained in the earlier chapters, when they had three days off after the first floor)
