This is the classic adventure, and although it's an old chestnut it's still worthy of attention, especially from Camputers Lynx owners who have so little choice when it comes to software.

In order to fit the large amount of data needed for all the locations into the small amount of memory on the 48K Lynx, much of Level 9's program has been located in the video RAM. Because this is a text-only adventure, this doesn't matter so much, but it has some interesting side effects.

The first occurs while you're loading the program - the screen changes colour and some very odd pixel patterns appear. During actual play, the text is shown green on a black background, but as soon as you enter text the screen 'snows over' in magenta, making the text virtually unreadable for a moment or two. The display then goes back to normal, and you can easily read the description of the location in which you find yourself.

One annoyance with the Camputers Lynx in playing text adventures is the lack of scrolling, and sometimes when the screen is full it can be a bit confusing.

All these grumbles fade into insignificance, however, when you start to play. The locations are very fully described, the variety is enormous, and the possibilities seemingly endless as you explore a vast network of underground caverns for treasure.

Although by contrast with some programs available on other machines this program looks a little dated, it shines out like a star in an empty sky as far as Lynx owners are concerned.
