Knock, knock. Who's here? The Doctor's back, in search of The Key to Time.
This new text adventure from Lumpsoft features the veteran time traveller and many of his oldest enemies, battling it out through time and space. Davros, Daleks, Cybermen and fellow time-lords all show up as you steer your Tardis through the ages.
With the aid of a timescanner you must discover the scattered pieces of the great key and presumably save the universe into the bargain. Before you can begin the quest you will have to learn how to operate the Tardis.
Addicts of the TV series will find themselves in a well-known environment but the program is very friendly and will give considerable help to those who are less familiar with the bumbling doctor.
The program is responsive and versatile whilst the riddles are by no means obvious. It will get you zipping back and forth through time like nobody's business.
The Key to Time is good-humoured, well written and a joy to play.
