Maze of Madness is a modern game for an ancient computer (namely the 8-bit BBC Micro, which this blog seems to endlessly bang on about).
Well, I say “game”, but it’s more of a demo – a demo of a rather cruel puzzle. But it is actually solvable, if you spot the trick.
Mathbrush, the Official Unofficial Historian of IF, said that he’d never come across any other game that uses the gimmick that’s used in MoM. Whether that’s a good thing or a bad thing is not for me to say. Because unfortunately I’m the author.
You can play the game online.
