Howdy! I’m a ZZTer with some recommendations of my own:
– CAT, CAT, THAT DAMN CAT (2009) – Neat hybrid of a sort of Game-and-Watch style game and adventure game. (There’s a slight bit of action at the very end, but the game’s basically done by then.)
– ZZT Encyclopedia Online (2001) – Not a game, but a large reference of things one can do in ZZT by clever scripting and taking advantage of its quirks. Some of the info is dated or inaccurate, but 10-year-old me was fascinated by the ingenuity on display.
– The Secrets of Raventhorpe Manor (2025) – A silly riff on the old “purple key” worlds of yore. You might get a chuckle playing one this after suffering enough through those.
– BUYSO (2020) – Christmas shopping at not-Daiso (oops this would have been topical in December). (Also, I made this (sorry for the self-promotion).)
– Play ZZT (2025) – This is a Weave game that reimagines the original 4 ZZT worlds as a deckbuilder (dicebag-builder?). There’s a bit of a learning curve, but it’s not too hard once you get the hang of it.
There’s plenty of more stuff out there, but these are a few things that immediately come to mind.
