Screensaver
The Home Screen, On Your Desktop
The Cosmic Shore Home screen as a free screensaver: vessels chasing the crystal through the Garland. It runs on its own, with no game, no account and no internet, and it sends nothing anywhere.

“Windows protected your PC”
This early build is not code-signed yet, so Windows shows a blue warning the first time it runs. Click More info, then Run anyway. Some antivirus programs are wary of unsigned screensavers too. A signed build comes later, and the warning goes away with it.
Good to Know
Do I need the game installed?
No. The screensaver is a separate download that runs on its own: no game, no account and no internet. It sends nothing anywhere.
Can I try it without installing?
Yes. In the extracted folder, right-click CosmicShore.scr and choose Test. Move the mouse or press any key to leave. Double-click it to open its settings.
What can I change?
In Screen Saver Settings, click Settings… to choose the frame rate, which screens it runs on, and the wide or close-up camera.
Will it drain my battery or slow my PC?
It is built to be light. It draws 30 frames a second by default, uses the power-saving graphics chip where there is one, and stops when you come back.
It says WebView2 is missing.
The screensaver draws with Microsoft Edge WebView2, which comes with Windows 11 and nearly every Windows 10 PC. If yours is missing it, the screensaver offers Microsoft’s download page.
How do I uninstall it?
Pick another screensaver (or None) in Screen Saver Settings, then delete C:\Windows\System32\CosmicShore.scr. To remove its settings too, delete the Froglet\CosmicShoreScreensaver folders in %APPDATA% and %LOCALAPPDATA%.
