Demo of the ZZT World Editor

DEMO.ZZT, or Demo of the ZZT World Editor, is one of the six official ZZT worlds by Tim Sweeney, as well as one of the three worlds available as part of the shareware ZZT distribution. It serves a documentation purpose, introducing the player in an interactive manner to the elements provided by the engine. It has received no revisions after being originally released with ZZT 2.0.

This world is also notable for using an different color of water (blinking white on dark blue (0x9F)) than made available in the final version of the built-in editor (blinking blue on light gray (0xF9)).

Unlike all other official ZZT worlds, this world was made available under the terms of the open source MIT license as part of the Reconstruction of ZZT.
