"There are many improvements over the original version. I have updated many of my original graphics and made a few more. The mapping has been tweaked. A few scripts have been altered or added. Warp Magic has been added to make navigating some parts easier. There is more to do. A new area has been added including a new fight. Paul Pliska's Farmer attack graphics has been added. A new sound has been added. Some secret areas have been added. A few subtle hints have been added."
