Rooms with anomalous slides all over the place.
In the Sliderooms, who knows where you'll be swept off to! These rooms all contains slides that either brings you somewhere else within this level, or to other levels entirely.
Other than the unpredictable nature of the slides, the environment is stable and the rooms vary in style and size.
This level is devoid of entities.
Entering and exiting this level is unpredictable (hence the "Extreme" classification). You'll either arrive here via a slide from another level, or you'll slide into a random level.
