What the June 2026 update added

This was the first demo update since August 2025 and it rewrote how exploration plays, so older videos and guides describe a different game:

FAQ

Is the Shroom and Gloom demo still available?

Yes. It is a separate free listing on Steam (app 3602770) for Windows and macOS, and it stays up alongside the Early Access release.

How long does the demo take to finish?

It runs 26 handcrafted tunnels and ends at The Gloom. The fastest recorded run on speedrun.com is 16 minutes 5 seconds; most players need several attempts because dying restarts the descent.

Is the itch.io version the same as the Steam demo?

No. The itch.io release is the September 2024 prototype, made in three months, and it predates the June 2026 exploration rework. The Steam demo is the newer build.

Coming from the demo? The card list transcribes what is on the cards, and the exploration guide covers camping, hazards and the pressure The Gloom puts on you for lingering.
