ZZT (video game): Difference between revisions

** If a program dies and the next stat has a direction, it will move if not blocked. This is usually undesirable, but it is possible to mitigate it, and to take advantage of it.

* [[Interchangeable Antimatter Keys]]: Mostly - keys come in 7 colors, but if you already have one key, another key of the same color cannot be collected and will instead block your path (although they are still indirectly pushable). Many puzzles are deliberately centered around this behavior.

* [[Level Editor]]: Most people agree that this is the best part of the game (much to the surprise of the game's creator).

* [[Locked Door]]: The original episodes revolve around getting purple keys to reach the final area.
