This is a remake of a game on the MSX (asw well as MS-DOS) called King's Valley, although with a Doctor Who theme...

You portray the fourth incarnation of the Doctor (Tom Baker)

The object of the game is to collect the coins on the 23 levels

To get the coins you need to break away the stones using the drill or open the hatches using the sonic screwdriver which are scattered around the levels, 'you cannot jump while carrying tools'.There are crates to help you to reach anacsesible places (IE:you push them around)

you must aviod the Cybermen or you will need to try again. On later levels there are also one way doors

on the 23st level using the mouse there is a puzzle for you to solve to finish the game.

This game among many others is available at PJ Crossley's own personal website: http://pjsfreeware.synthasite.com/
