In traditional adventure style, you play a treasure seeker, in this case aiming to score 1024 points. Your journey takes you through forests, over and under mountains braving deserts and ravines. You will encounter elves and dwarves, dragons and witches, and droves of rather nasty guards and gorillas.

TWIN KINGDOM VALLEY is not one of those adventures where you must spend three weeks pondering how to escape from the first location. In fact about 100 of the sites are easily accessible by the usual direction commands.

You'll have no problem finding the lamp which you will need for the tunnels, or a bag for carrying things. If you do get a bit stuck then typing HELP lists all the verbs you can use.

Some of the other travellers you meet are a nuisance, not only to your quest, but also to the smooth flow of the game. Some can be helpful, but if in doubt, check your own strength and indulge in a little violence. The best cures for weakness are waiting around or swimming in Watersmeet.

One technical feature of the game is seriously amiss. With a Plus 1 fitted, the save game feature doesn't work. The most annoying part is that without a saved position there is no restart option, so you have reload the entire game. Even when it does work, saving a game is a long, long process.

Despite its shortcomings, I like this game. It has an interesting atmosphere and it straightforward to map. TWIN KINGDOM VALLEY is a real bargain, and is one adventure I am determined to solve.
