Jet Set Willy is a computer game originally released in 1984. It was released first on the ZX Spectrum, but was later released on multiple platforms. It is a sequel to Manic Miner. The plot is that Willy had bought his new house with the money from the previous game, but it is unexplored and full of what are probably the previous owner's experiments. After a celebratory party, the place is chaos and his housekeeper Maria won't let him go to bed until he sorts it out. Willy must tidy up the mansion so he can get some much needed sleep. A very faithful java version can be played here.
