Jet Set Willy in Altered Reality is Norman Sword's JSW game which uses Matthew Smith's original code as its basic core and runs in the original 48K, but thanks to extensive compression and rewrites of the original code features a significant number of enhancements and new features.
Norman Sword released several versions of the game which show its development and the logical progression from version to version.
Version K (JSW128 VK) was a completable version introducing several aspects of gameplay and 128 rooms in 48K. It runs at double the original speed, with up to 16 sprites per room and up to 32 arrows per room. It features diagonal sprites, mid sprite bounce and homing sprites, among other novelties. The last revision of this version was JSW128 VK3.
Version L (JSW128 VL) was an extension of JSW128 VK3 "pushed towards the feel of Manic Miner". It introduced portals, changing the way Willy re-appears back in a room after death: he is moved back to the last portal he visited and the game re-installs all the items collected since. Some features (like the superjump) were removed. The last revision of this version, called JSW128 VL5 demo, updated the game structure completely, allowing for a dramatic increase in speed.
Version M (JSW128 VM) has the ability to switch between the two basic game formats: the standard "die and re-enter the room" solution used in version K and the "die and emerge from portal" extended logic used in version L. Version M is Version K and Version L combined. According to Norman Sword, in essence it supersedes both of the earlier versions. It features 128 rooms, triple speed, multiple game options, a game options menu, 16 game characters to use, the ability to use portals, the ability to change start rooms and an extensive in-built cheat.
