Nitemare Park by John Henson is an Abyss clone; a kind of map-based quiz with lots of random elements creating a frustrating series of tasks with the player given one and only one chance to get the answer right each time.

Games of this type originated with the Commodore PET and, frankly, no matter how well they are done, there is no getting away from the very dated and pitiful things these were capable of. This isn't just my opinion; when Merlin reviewed Abyss in Electron User, he thought much the same.

At a snip, it's worth a look and it's more based on a bad idea than it is a game done badly. However, only real fans of computer nostalgia should bother. Anyone younger than twenty is simply liable to laugh out loud before depositing the cassette in the trash.
