Jet Set Willy
Jet Set Willy is a platform game in which the player moves the protagonist Willy from room to room in his mansion, collecting items. Unlike the screen-by-screen style of the predecessor, the player can explore the mansion at will.
Story
Willy, a tired miner, has to clean up all the items in his house after a big party. When that's done, his housekeeper Maria lets him go to bed. Willy's mansion was bought with the wealth from his adventures in Manic Miner, but much of it is still unexplored and it seems to be full of strange creatures, possibly from the experiments of the (disappeared) previous owner. Willy must explore the huge mansion and its grounds (including the beach and yacht) to completely clean up the house so he can get his much-needed sleep.
