 The brilliant prequel to Jet Set Willy sees Miner Willy battling through the robot-filled underground mines of Surbiton. Fast, colourful graphics and very weird enemy creatures. You are chased by deranged robots, pirouetting rabbits and mutant toilets as you race to collect enough keys to escape? And they aren t your only problem because there s limited oxygen in each cave, so move it or be asphyxiated.
