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.
