While travelling in time you have become separated from your Time Machine and you don't know whether you are in the future or the past.
Your only chance is to find the Time Machine to return to the present.
Notes
Although this game is listed as being written with The Quill, the game was actually coded in assembler by Graeme Yeandle; it was only later that the code behind the game database & interpreter was developed into the standalone Quill adventure creation system.
Graeme Yeandle later produced a DOS version of the game, running under his PC version of PAW.
Kind of a short proof of concept for what was soon to be The Quill.
