As outlined by seleste [developer] on Steam, the easiest way is to:
"From your Windows desktop, press the Windows key + R together. This will bring up the “Run” dialog. Type in %LOCALAPPDATA%\GlimpseGame and press Ok.
This will bring up a File Explorer window showing the directory where the game stores its local data. You should see a folder called Saved."
Thanks selestefor posting that!
