I had starting to make Super ZZ Zero, which is another ZZT-like. A lot of it is not implemented yet, though.
If you have comments/questions/complaints/suggestions/etc about it, you can write it, on here or on GitHub or on NNTP. This software is public domain.

I have set up a NNTP to discuss ZZT and other stuff.
