You pilot the Nano Fly in to the Nano-Tech Tower and hopefully out again. It is no easy ride though. While inside your aim is to destroy as many of the purple floppy disks as possible! There are a number of items to help you. These include extra flies, energy replaces, rocket decoys, restart points and various other stuff. Up against you is the Tower's security system. Be careful not to get squashed, blown up, or wet! You would think that because of this danger your fly would be spanking well tough, but it's not. Bumping the frail little thing in to anything will cause it damage (indicated by a red line) as will standing near your own exploding bombs! The Tower is made up of a number of large areas, each containing a disk. Certain areas have multiple exits. It's up to you to find the best route through the tower to destroy the most disks. And take note: you can't return to any area you have already been in. COMMERCIAL QUALITY!
