From the game inlay card "You fall into a deep sleep after a hard day and find yourself trapped in this graphic, text and icon driven adventure from which you are unable to wake. You must travel through the land of 'Zzzzzz' to find and cross the border post to return to this world, or wander lost in your dreams for months. To awake you must solve the many puzzles presented to you with a little help from the Sandman by using the keyboard and icons." User Summary Zzz was developed by Clive Wilson and Les Hogarth.
