As an interplanetary secret agent, you must roam the galaxy in your extremely fuel-conscious space ship (only 500 gallons to the nearest planet). Heaven knows what sort of engine your ship possesses, but as stars scroll past your cockpit you can hear what sounds like a very unhealthy motor-scooter in the background. There are some touches of dry humour, including an interminable queue of people that you can stand in for ever, never quite reaching the end. You'll also have some trouble with a certain crazed dwarf and some unstable stalactites -- at least if you go the way I did. A 'living tutorial' helps new adventurers get into the swing of things.
