The object is to escape from a building
to a safe black square before a time bomb explodes.
The Building - an outline of a
building is given in blue with some of the doors only one pixel wide.
Extra rooms, corridors and, sometimes, doors are seen at and above
levels three and five. The blue walls must not be touched at any level.
The Timer - is ticking away at the
bottom of the screen. It is reset if the black square is reached or if
the bomb explodes. If a life is lost then the timer continues from the
same position. It is not reset to zero. On each new level the timer's
fuse is shortened and is not lengthened again during the game.
The Player - leaves a red trail
which must not be touched. The joystick directly controls the speed of
the timer - as long as the player is moving, the timer is slowed down.
It is a necessity to keep moving at level 5 and above. Lives - the game
starts with three lives and a life is lost if a red or blue square is
touched or if the bomb explodes. If a life is lost then one level is
also lost and the game continues at this easier level but with less time
General - an average score of
55,000 is easily possible reaching level 6, however progression beyond
this point is difficult and requires expert joystick control.
