About the project

20 Minutes Till Dawn is a roguelike survival shooter by flanne. The web-ports build credits bog and rah (fern/truffled) and ships a Unity WebGL canvas with its data and WASM parts bundled in the repository; the linked gn-math demo provides the browser entry.

Technology: Unity WebGL / WebAssembly

Getting started

  1. 01

    Open the gn-math browser demo for the web-ports build.

  2. 02

    Wait for the Unity canvas and click inside it to give the game focus.

  3. 03

    Use the game’s own controls/settings screen to confirm the current keyboard or controller mapping before a run.

Before you play

The originally listed truffled URL currently renders an unrelated US Government page, so it was not used as evidence. The public web-ports repository and its Unity index were reviewed together with the linked gn-math demo; gameplay, save recovery and device compatibility were not tested.

Questions & requirements

Do I need game files?

The reviewed browser demo loads a prepared Unity build and does not expose a local-file or ROM chooser. The original game and assets remain the rights of flanne and its publishers; this directory supplies no game files.

Has this build been tested here?

The linked author's documentation was reviewed on 2026-11-09. A complete gameplay session, save recovery and device compatibility have not been independently tested. Supported controls below are documentation claims.
