I'm guessing I could release mine to the public. (please note:It was made pre-zdoom 2.1.0 so some of the features could be done better now. This also makes some sprites have the evil pink line error as then I didn't have a way to properly extract alpha sprites)
To make the interactive features work, you need to bind some keys at the menus.
However, it isn't exact.
1.Imp and Demon sprites aren't the original
2.None of the simple solid color textures
3.Textures can only be cycled one way
