About 20 Minutes Till Dawn
Survive 20 minutes of Lovecraftian horde waves with aimed shots and synergistic upgrades.
20 Minutes Till Dawn (2022) by flanne is a roguelite shooter: you aim and fire manually while monsters close in, and every level-up offers upgrades that combine into powerful builds before dawn breaks.

How to play 20 Minutes Till Dawn in your browser
- Press Play in browser — the game opens on gn-math.dev in a new tab.
- Wait while the game files load. The first start can take from a few seconds to a few minutes depending on your connection; later starts are faster because the browser caches the files.
- Click inside the game window so it captures the keyboard and mouse, then switch to fullscreen (F11 or the host's fullscreen button).
- Open the in-game settings to adjust controls, graphics and sound. Progress is normally kept in your browser storage, so don't clear site data if you want to keep your saves.

What to expect from the browser version
The browser version of 20 Minutes Till Dawn is an independent web project — a port, recompilation or fan remake — hosted on gn-math.dev. It is not an official release from Erabit Studios, and MePlayable does not host any game files: we describe the game and link to the project.
Because the game runs inside a browser tab, some features of the 2022 original may be missing or work differently: online modes, cutscenes, saves, mods and graphics options depend on the build. If something doesn't work, check the host's own notes.
Requirements
A modern desktop browser — Chrome, Edge, Firefox, Opera or Safari 16+ — with WebAssembly and WebGL enabled, at least 4 GB of RAM and a stable connection for the first load. Hardware acceleration should be switched on in the browser settings.
If 20 Minutes Till Dawn doesn't start
- Black screen or endless loading — update the browser, enable hardware acceleration and reload the page with Ctrl+F5.
- No sound — click inside the game window: browsers only allow audio after you interact with the page.
- Lag or low FPS — close other heavy tabs and programs, then lower the resolution or graphics settings in the game.
- The site doesn't open — the host may be temporarily down or blocked in your region. Try again later or use another project link on this page.
