Jet Set Willy

Cult hero Matthew Smith followed up Manic Miner with a seminal platform game. Having struck it lucky in the first game, Willy now owns a lavish mansion with over 60 rooms linked in a 3D plane, and must tidy it all before his housekeeper will let him sleep.

Each room has its own hazards, such as spikes, revolving razors and ropes. The route through the house must be navigated carefully, due to the multiple entrances to some rooms - this is perhaps the first action game where mapping is an advantage. Another innovation, to the chagrin of players everywhere, is manual protection - a sheet of colour-coded numbers.
