A few trends come to mind:
Retro PC experiences - I noted during IF comp this year that games that imitate old computer systems seem to be trendy. Two games outside the IF scene—Hypnospace Outlaw and Stories Untold—were both well received this year with releases on most major game stores; they have excellent presentation as well.
Bitsy - I just started a thread on this. Bitsy is rapidly approaching Twine’s level of popularity among developers and it is gaining quite a bit of press coverage too.
Playstation-esque games - The Playstation-style low-poly aesthetic is in vogue. Right now it is mainly being used for horror games, but the trend could also mean more separate narrative/gameplay experiences in the style of Metal Gear Solid and Parasite Eve once again. (As I understand it, Bioshock popularized during-gameplay audio logs and that style is still very popular today).
Cinema-style games - Not cinematic platformers or FMV games, but games that draw heavily from film and star notable actors. Twelve Minutes, an interactive thriller featuring the voices of James McAvoy and Daisy Ridley that was showcased at the Tribeca Games Festival, is one recent example of this.
Audio games - The Vale: Shadow of the Crown this year was released as a game for the blind. It’s not the only game to do that (one of the first was Kenji Eno’s Real Sound: Kaze no Regret in 1997). This is pretty niche but I thought I would mention it.
Crypto funding - Though some people in this thread have mentioned NFTs, I think it’s more likely that more games will be funded through crypto. Twitter has integrated Bitcoin tips; I think it’s only a matter of time before Itch.io and other platforms do the same. This is not specific to interactive fiction, of course.
Big’s Big Fishing Adventure 3: The Trial - Somehow this unlicensed for-charity visual novel based on the Sonic franchise managed to get two official actors (Mike Pollock as Eggman and Roger Craig Smith as Sonic) to voice their characters. Not advisable, but impressive.
