Variety, a game released on May 22nd, 2020, contains a fork of ZZT by WiL.
There is a customized VZZT.EXE available for use. […] Run VARIETY.BAT to use it. It is not required; the game is fully backwards compatible and will play just fine with vanilla ZZT; however, it adds a number of enhancements to the experience.
VZZT.EXE makes the following changes to the ZZT engine:
Üto be displayed in place of the torch number, and set the torch cycles to 30,000 (which is already set by the VARIETY.ZZT world file).
Üwill either indent itself by one character or turn from yellow to black. Both of these will be undone the next time the player scrolls the window.
infectedis set, the player color changes to white-on-black and begins to alternate between white and light grey, along with occasionally flickering between characters 1 and 2.
dreadis set, the player color changes to dark grey and begins to rapidly switch between text characters. At the same time, the gameplay status bar numbers and key display will be changed to flickering, garbled text. Should the player quit the game, much of the title screen menu will be covered in the character
Ü. Note, however, that the gameplay status bar change will only occur if the torch cycles are not 0, and it will only animate if the torch cycles are exactly 30,000 (which is set by the VARIETY.ZZT world file).
hypeis set, the engine will run at turbo speed, as if an endgame event had occurred. If the flag is then cleared, the engine will return to whichever speed setting the player used.
