Livestream of the ZZT worlds:
"Island of Doom" by Sam Hockaday (1997)
"The Forest of Magic" by Mark McIntyre (1995)
"The Jungle of Evil" by Mark McIntyre (1994)
Three more unpreserved worlds in various locales. Island of Doom is a very Lost Monkeys inspired world with a few fun ideas like using a watchtower to learn what's in each direction you can travel. Forest of Magic is a loose conversion of Super ZZT's Lost Forest to ZZT that wasn't quite as polished as the source material, but a good early effort. Jungle of Evil is a level-based action game that's a bit too simple to really get a lot out of it, but the challenges presented are reasonable enough when it's not your 4th ZZT game in a single stream!
