This is the "Soft" Weave, keeping the same logic as ZZT 3.2, bugs and all, but giving you some control over how things look and the quantities associated with items.
This is the "Firm" Weave, using the same code pathways as ZZT 3.2, with fixed bugs, the same control over colors, messages and sounds as SoftWeave, and some expanded options for your ZZT worlds with a few added commands, directions, and other features. Check out FIRMDEMO for more info.
Softweave 2.5 expands on the foundation provided by Softweave 2.2, including a unified and improved configuration format, fixing a handful of classic 3.2 bugs, and improved handling of player clones.
