Jill of the Jungle

Jill of the Jungle is the first version of the engine which would go on to power Xargon. It supports CGA, EGA and VGA graphics by way of "colour maps", which dictate the CGA and EGA colours to be used to display each of the possible 256-colours of a given image. This way only a single 256-colour image is supplied, rather than a different image for each display.

Jill is also unique in that it is one of a very small number of games that include a level editor, albeit an undocumented one. See the tutorial for more details.

Notes

• Since the level files are used for a lot of different things, you can e.g. swap INTRO.JN1 and 1.JN1 and then when you load the first level you'll be playing the intro screen. The demo and help screens can be accessed in the same way.
• You can also press Ctrl+P on the main menu to play the intro level, and Ctrl+E to enter the level editor.
