Jet Set Willy Editor

The Jet Set Willy Editor is a PC-hosted program (it works on Windows, Linux and BeOS). It can edit games based on the original Manic Miner and JSW engines, or my improved JSW128 and JSW64 versions.

JSW64 is a newer extension of the Jet Set Willy engine for 128k computers; it allows fewer rooms than JSW128, but more sophisticated room layouts.
