What makes Overgrown Depths different

Layer five is Overgrown Depths, also called the Jungle. The current Layers entry contrasts thick vegetation, edible plants, tree sap and groundwater with the earlier dry areas. It has no turrets or landmines in its listed trap set, but that absence does not make it a rest area. A larger creature pool and Elder thornbacks make combat awareness central. Search plants and supplies with a visible escape route rather than letting vegetation hide the next hazard.

Enemies and traps to recognize

Its documented enemies include shade crawlers, sand stalkers, cave ticks, overgrown ticks, tentacle-plants, thornbacks and the Elder thornback. Its trap list includes geysers, jump pads, spikes, bear traps, cave-tick spawners, skullcrushers, banana-plants and coils. This combination distinguishes it from a layer that can be summarized as merely a larger first cave. When the impending-doom warning appears, prioritize a route away from the Elder instead of finishing a craft or collecting one more plant.

Resources do not remove temperature planning

The current community temperature panel supplies an average of 21.8°C, a maximum of 31.5°C and a minimum of 5.6°C. Those are its simplified default animation-curve values, not a live reading or a guarantee under every run modifier. This corrects the old research gap that treated layer-five temperature as unpublished. Prepare for variation while deciding where to recover; the availability of sap or groundwater does not prove a comfortable sleeping site.

Progression and the old demo limit

The general layer rules describe a three-hundred-metre layer height and a bottom transition offering continue or save-and-exit. Height is not a cumulative depth measurement for this location. The full game continues beyond layer five into Frozen Chasm; the old demo instead looped after its fifth layer. Keep those versions separate when an older video calls the Jungle the end. The eleven-layer index describes later progression, including the final upward ascent, without turning a demo route into a full-release ending.
