You are issued with a personal code and a reactor start-up code. Once you have started, the reactor problems develop, and it's a race against the meltdown time to prevent the inevitable big bang.
To do this you have to find your way through the maze of rooms, overcoming problems on the way to locate a Time Machine. This machine allows you to go back in time, if you know how, to a point where you can prevent the catastrophe.
There are three levels of difficulty for the game and I reckon even the first will take many hours to solve. Still, depending on how well you do you may get a medal.
Once you start moving through time, however, its a different story. Some of the building work may be different. There can’t be many games where you need separate maps for different years."

It's unclear whether it was an actual adventure game or more of an RPG.
