I just released a silent update. If you download the latest version, I've added a Quit to Desktop to the main screen
Ah! Are you playing in full-screen? You're absolutely right.
If this means "you can't quit the game cause you love it", then thanks that's really sweet!
In case you're being literal, then the Quit button is at the top right of the level screen as shown in the video.
If you don't see it there may be something wrong with your display ratio, please send more info!
