The seventh floor had to use the entirety of its energy to make the dimensional portal stable, so Noah and the others couldn't seize any of that fuel. The event also revealed that the insects had been a challenge, but they couldn't be sure if they had arrived during the Labyrinth's creation or afterward.
The flying insects might have affected the floor like the turtles did with the sea. They might have changed the area's nature, forcing the Cursed Labyrinth to adapt the challenge to its new shape.
Noah couldn't find answers to those questions since the dimensional passage absorbed every clue that the seventh floor might have. Only a maimed version of the space-time array remained after the door to the next area stabilized, so he suppressed his curiosity to advance the exploration.
