Willy's New Mansion SE


 Willy's New Mansion is a redesign of Matthew Smith's classic game Jet Set Willy,

created by Daniel Gromann.

The Original Edition was designed in 2004, using John Elliott's Jet Set Willy Editor (JSWED)

v. 2.0.3, and the vastly improved Special Edition - in 2016, using JSWED v. 2.3.7.

Please see the accompanying text file for detailed credits, acknowledgements,

disassemblies, technical description and all other pertinent information.

Willy's New Mansion is FREEWARE.

The Special Edition is the final, complete revision of the game. While the ZIP

of the OE is included in the ZIP of the SE for completeness, everyone who has

not played the game before is encouraged to play the Special Edition.


You can also download complete RZX walkthroughs of both the Original and the Special Edition

or watch a video of it on YouTube.


(This video shows a walkthrough of the Original Edition of the game which is inferior to the best publicly available RZX recording)

where you can see a screenshot gallery of the Special Edition,

or you can have a look at a screenshot gallery of the Original Edition.



Please, let me know you have played Willy's New Mansion SE! Share any

comments you may have, or just drop me an e-mail to let me know you have played the

game, without any specific observations. The biggest gratification and encouragement

for anyone designing free games is to know that someone else has played them!
