What this layer is
Crimson Ascent is the eleventh and shorter layer, described by the developer as part of the endgame rather than another full descent. It is associated with an ascent back toward the surface and an optional bonus ending sequence.
The known flora includes Crimson Bushes, Crimtrees, Pus Sacks, Veins, Leadbushes, Brownshrooms and Glowshrooms. Beyond that, the layer is intentionally unrevealed. The full game launches November 9, 2026; this page will be updated with verified details after release.
Pre-release information. This layer is not playable in the demo. Details come from developer updates, community datamining and pre-release material, and may change when the full game launches on November 9, 2026.

- Expect the optional ending sequence to demand a specific route or item.
