Cybergrid

The Story:
Hack your way through a rival corporation's computer systems, their security daemons looking for any sign of unwanted programs.  Read the each sector completely before moving on to the next one.   Access a glitch and trick the system into seeing you as the daemon removing it's defenders from the system.  Move fast though, they'll reload and return to defend their systems.  If you feel like they're getting too close, cross a firewall and rejoin the network elsewhere in the system.  If you're lucky you'll see a zip file, read it for a large cache of data.

Gameplay:
Use the arrow keys to move your cursor through the system attempting to collect all the dots and moving on to the next round.  Avoid daemons to stay in play.  Cross a glitch to make yourself invulnerable and destroy the daemons instead.  A bonus appears in the middle sometimes, but is not needed to finish a level.
