Sorry for the confusion...
I played the game last in the year 1993/94, it ran under DOS with VGA.
In the game one should steer the blue crosses into the energy
field whereby the crosses after clicking up to the next
obstacle (for example a wall) moved.
In the course of the game were added more crosses and obstacles
and became more difficult.
It was developed by the company Fairlight, unfortunately gives it no longer.
