This is a fun question to get... there's a lot.
People really do make so many different kinds of projects...
Alright, here's some new hotness from the recent game jam, some slightly older projects that jump to mind, and some personally sentimental decks.
@HarlequinDiver's Asleep in the Deep has really cool 3D backgrounds as the card art. I suppose it's an escape game in terms of genre? Little puzzles, spookiness, bits of whimsy with the portraits on the walls. It's so cool.
@Sysl's Deckerware: Eggbug Party Games An amazing variety of minigames that come at you fast. With Eggbug! The fact it's unlocked (the menu is visible) on the page also means you can just peek under the hood of any section you find interesting to see how it was made, which is great.
@Sysl also made Broken Gate which is a solid template (with documentation of how to use it) for a very classic adventure game format.
@Gray-LoFi's In Dreams of Strife is a cute little story WITH A BATTLE SYSTEM. There's animations during the fight and you can unlock skills and... I'm still pretty excited about this.
@AirGong's Self Portrait: Vomit on Concrete -- okay definitely read the warnings on this one, it was made for a jam themed around mental health. Parts of it are a bit heavy (and there will be vomit on concrete), but it's memorable and in the end I think it's very tender.
@fish's Eider Cake this was originally published in Indiepocalypse #53. A scullery bird in the kitchen of a medieval bird cloister(?) is asked to search for a missing recipe that is needed for the patron saint's feast. What's not to love? The style is great, the writing is lovely, and it's an incredible concept.
@x-0's Tough Baby This thing is wild. Help your friend at art school. The animations, the dialog, the.... vibes. It's so big and full of surprises everywhere. And then of course.... there is the Tough Baby to deal with.
@ednaarel's te/ra/to/ma Another 'check the warnings' moment. A heavy personal story (re: medical things) with some very effective use of pacing and visual emphasis.
And while I am doing a tour of recent-ish work by our local decker-ers, @vermis's Ontological Mystery is a killer little tale with two endings -- and you should definitely see both of them.
And @floconsugar's Thoughts from inside my brain is a very charming wiggly zine.
On a more personal level, because we're talking favorites. @Milliesquilly's Zine of Millie got me into Decker in the first place.
@sirboxalot's CUBICLES is a pixel hunt through some very unusual, uh, office cubicles. There's some little jokes and things while you're looking for the clicky bit that leads to the next screen... but also it's a favorite because he made a lot of it while he was streaming. And I was hanging out in chat. Being able to see someone else drawing in Decker helped me a lot so, yeah. I'm very fond of this one.
@lokeloski's Deckstamp is a very handy tool for importing color images from the recent jam -- tools matter! A lot! I'm thrilled.
I am also technically allowed to say @Internet-Janitor's Puppeteer module. This thing opened up the door for me to mess around with some neat animation tricks, which was huge. (Modules are also... made in Decker)
If there's a cohost screenname, I can't remember it... but in Coral Nulla's Don't Save Me you are given the 'role' of manic pixie dream girl by the Agency of Narrative Intervention. The story goes some interesting places. And it is really visually lovely for a text-based game without art assets.
Thank you for the question 
sorry for listing so many, but... y'know. There's a lot to like.
