Half of the map, and some of the related puzzles, are almost identical to Steve's Monster's Final Hour which was a port of a John R. Olsen game.
The game has been adapted for expanded VIC-20.
Barry Hart produced an unofficial port of the Spectrum game to C64 in 2020.
The game was ported to the BBC Micro by Lee Newsome in 2022; see here.
