I can't find this mentioned here, which is a pity because it's too late to actually enter, but a heads up: ParserComp, a competition for parser-based IF/text adventures, has been revived this year for the first time since 2015. The games are now available for playing and judging (you'll need an itch.io account to judge): https://itch.io/jam/parsercomp-2021/entries

(Disclosure: I'm an entrant in the competition. But you should look at any play whichever games you like - there are 18 of 'em.)

Share and Enjoy!
