Oh, I completely forgot about the short games showcase! This year’s showcase had two in particular I very much enjoyed:
You Can’t Save Her. Good design, just generally a good and fast-paced one to play.
Suspended in the air so that all of your weight is concentrated on a single point halfway down your spine. Tense and well-designed. Worth a try, for sure.
I’m literally the only 5-star rating on there out of 30-something so it’s definitely a matter of personal preference!
Some of my favorite tiny ones! (I’m talking super tiny here, like a 5-min playtime.) Will likely add more later. I like little games that do a lot in a small space, that feel perfect as they are, no need for expansion. Also, as a big replayer of choice-based games, I like when there are multiple paths so that I can play again and explore other options. I also like games that make me deeply feel something, that capture an emotion I can relate to.
Max already mentioned Suspended in the air…, so I’ll add that I also quite liked this one, the third in the RGB Cycle (Suspended in… is the second).
I mean… read the description! What’s not to love! 
MY EMOTIONS.
A lot of my fave bite-sized games have been mentioned here – NYX and Chinese Family Dinner Moment are on my top list of short games, and here are some from the same authors that I’m very fond of.
Lush prose and a brief look into something larger–I love the depth and layers of emotion explored in here. Despite the 2nd person POV, there’s a sense of being allowed this glimpse into the relationship that is the focal point of the game, which I think sets up a really interesting position for the player to explore all the variations from.
I enjoy a lot of Kastel’s work because of the way emotion is often presented raw and blunt, as it is, and the player invited to make of it what they will with whatever context they have gleaned or synthesized from the game itself. The framing feels very clean to me in the same way; the meat of the game is the meat of the game. I MUST EAT CHILI OIL is evocative but it’s up to the player to translate what exactly is evoked within themself.
In a similar vein, I think Autumn Chen’s succinct, precise writing really shines in All or Nothing. The way she handles distinct character voices here and the slow (or not so slow, depending on how you play) shift and blending of them is delightful. This is a little longer than others I’ve mentioned here, perhaps pushing the “super-short” category…
Incredibly atmospheric and rich. I adore this game–a haunting for every one of the senses. There is something deeply human in the bones of this game and the player must reflect on what kind of contrast their own flesh offers in the playing of it. I particularly enjoy the way the player’s agency is framed.
Hehe, a bite-sized treat of Gothic romance. The genre pillars present in this game frame its array of emotional pulls beautifully–the tenderness exists not despite the horror and the grotesque, but alongside it and perhaps even because of it.
I wanted to post about one of my favorite short games that came to my memory:
To Spring Open was a Shuflfecomp game that really captured my imagination. It’s fairly short but it’s a Twine game with a cool outfit-changing mechanism in an alternate history setting.
Constellate was pretty good, quick and short 
I almost with it were longer but then it wouldn’t be a short game hehe
