Blind Alley depicts a sport set nearly a millennium from now, in which you are
in control of a spacecraft and must defeat opposing craft. Gameplay resembles
the Tron Light Cycles game, being played out on a grid, with more and more
ships as the game progresses. Each craft has its own motion trail, which
remains on the screen throughout the game, and a round is lost by a ship which
hits one of these trails or the screen border. Control is directional rather
than rotational, so attempting to reverse is fatal. This version has no
2-player mode, but supports Kempston joysticks and runs within 16K of memory.
