Jet Set Willy

This platform game is the sequel of Jet Set Willy. Again has each room 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.
