This game starts with a pleasant view of a house in downtown Surbiton, accompanied by a pleasant rendering of The Skaters' Waltz. After a few bars of this merry little tune, the control keys are displayed, and the computer goes into demo mode.
You can choose whether you want to watch this or play the game. The demo will show you every cavern your miner has to explore, this time to the accompaniment of another old favourite, Hall of the Mountain King.
I'm not sure what Grieg would have thought about one of his works being used as the background to a video game, but you have to hand it to them - it's very clever.
Each of the 20 caverns contains danger in many different forms. Platforms you jump on to crumble under your feet, there are poisonous plants, stalactites and various creatures which try to foil your plan of grabbin' the cash.
All the things you will meet are very strange and weird. There are robots, penguins, performing seals, Pac-people, mutant telephones, Humpties and toilets (yes, toilets, with seats a-flapping).
