Appears to have been originally designed for the Atari; where it was released by both Argus Press' Mind Games and Bug Byte. It was included on the Atari/Bug Byte "Compilation C".
Although advertised for the Spectrum, C64 and Atari... only the Atari 400/800 version is known to exist.
The Spectrum port may have been coded by Stephen Ward.
A good game, with great graphics. Only bad point? A lot of travels within this house.
