Reception.
Dick Olney for "Personal Computer World" said "Overall, this is undoubtably one of the best games of its type which I've played on the ZX81.
Arthur B. Hunkins for "Compute!" said "Mazogs is an excellent, single-player, treasure/maze game [...] Its full screen graphics make excellent use of the Sinclair/Timex capability."
Fred Blechman for "Electronic Fun with Computers & Games" said "Highly recommended - unless you already have high blood pressure."
