Eren and Levi's route takes them deeper into the building, where the scent of blood and decay is strong. After walking for a while they start feeling like the (wooden) floor is very, very unstable and actually breaks beneath them. Underneath the floor boards there's a pool of poison that will erode anything it touches. There are two doors: left and right. The closer they get to the doors the less floor there is to step on.

Reiner and Hijikata's route takes them into a corridor with a sturdy stone floor. They have to be careful, however, as they have a chance of touching a stone on the floor that activates a trap. This trap will make the floors start closing in on them in an attempt to crush them. There are two doors they can rush into if that happens: one left and one right.
