This is a good example of the 'random adventure' type of game, which provides a different scenario eyery time it is played.
In a given location, you can choose one of three directions which may take you along a passage, into a room, up to a door, down stairs, up stairs, or into a wall. You pick whichever of these you fancy. In the case of a door, you can open it, or listen first in the hope of hearing something that will warn you of what you may find inside.
Now and then, a monster appears, and there is a positive
plethora of different kinds, each with its own special
characteristics. There is treasure to be picked up, but you are
unlikely to be able to take it away with you, as a monster will probably
get you first.
With such a game, a nice balance between complexity and
pace is desirable. For my taste, the delays are just a trifle long,
and the combat oversimplified.
Despite these comments, the game has neat coloured displays of the
available options and occasional simple sound effects to warn you
if you press the wrong key.
