Phantasos by centuryglass
I don't think that Pico-8 will ever not impress me—I've seen games you wouldn't believe, to paraphrase Roy Batty. Phantasos is the latest to make me go "huh, that's neat", as it's a fairly fully fledged roguelike made in the teeny-tiny game program/platform. Pico-8 only features two action buttons, in addition to a host of other restrictions, so it's pretty impressive that centuryglass has managed to implement a full menu system, along with turn-based combat against ratty dungeon dwellers.
Holey Suit – to the Escape Pod! by Mitron
You don't tend to get that many physics-centric games nowadays, but Holey Suit is a new one that does excellent things with its constituent moving bits. You're an astronaut that, oh dear, has lost their precious spaceship, and in order to fling yourself back toward it you need to rely on your puffy jetpack. As in real space, you need to very careful with how much propulsive force you use, because if you go too far, too fast, it can be very difficult to work your way back. Real space tends to feature fewer laser beams or aggressive astro-bastards, of course, and Holey Suit is all the richer for it.
Planet Dysphoria by Andrew Howizon, Fishagon, Studio Thumpy Puppy
I can't tell you how representative Planet Dysphoria is of, well, dysphoria, but it's a lovely little adventure game set in a pleasingly boxy low-poly world. You're trying to find a way to escape a miserable situation, and your only way out is a big-ass rocket secretly harboured by your next-door neighbour. There's not really enough game to make the most of this next mechanic, but I like that the colour of the sky changes to reflect your hormonal state.
Eat Dots by Eurritimia and Svetlana
It's a fairly simplistic game, but I found a lot to enjoy about this colourful arcade nom-nom game made for the A Game By Its Cover Jam. The aim of Eat Dots, you see, is to eat them dots, while avoiding jerk lines that will kill you if you happen to make contact. Every time you snaffle a dot, you'll change to that dot's colour—which is quite a nice touch—while the game's soundtrack is catchy and upbeat.
The Last Supper, A Whodunnit by Ross Kevin Moffat
In The Last Supper, it wasn't definitively Judas who Judased Jesus in to the Romans—maybe it was Matthew, or Luke, or Chewie, or Dave. You have to finger the correct traitor in this strangely wordless detective game, by clicking on one of Jesus' bessie mates at The Last Supper, and then observing the information that pops up on the screen. This information will tell you where your suspects were, and where the Romans were seen, and while I wasn't able to figure out the right (randomly generated) culprit, I'm sure you'll do fine, as you are far smarter than me.
A Bathroom Myth by Anya Johanna DeNiro
A Bathroom Myth takes place in a world where sentient bathrooms exist: a place that is at once fantastical, but that has inherited some of the real world's prejudice. After an edict is passed down that says that bathrooms have to report transgender users to police, one such bathroom (you) is suddenly caught in a moral quandary, after a trans person enters, on the run from the cops. How will you react? Particularly when you've been told that death awaits the bog that doesn't follow orders? This an inventive slice of fantasy fiction, which goes where few stories fear to tread: to the humble commode.
