Had a long weekend so I upgraded from PS+ Essential to Extra (sub runs out Thursday, so it cost me a whopping 64 cents), looked up "best short games in catalog" and ended up playing these 4:
The Pedestrian
2D puzzle-platformer where you control a stick figure walking across a variety of traffic signs, screens, plates, chalkboards and street lights while a Pixar-y looking city bustles in the background. It gets points for presentation. The puzzles have you rearranging signs much like jigsaw pieces, tethering doors and connectors across wide open spaces while plotting your dude's navigation. They're fun to figure out, and having the playing field smashed into a number of smaller screens is a pretty cool effect. It starts getting a bit repetitive towards the end, but you get a neat mindfuck epilogue for your efforts.
Transference
Essentially a VR tech demo by Ubisoft (it took me all of 2 hours to 100%), though you can play it as a regular first person escape the room adventure game. It's pretty creepy but has nothing going on in terms of gameplay - you spend most of the "game" wandering around an empty flat, looking for flags to trigger and occasionally inputting a password. I imagine I'd get more out of it if I'd played the VR version. And I like Macon Blair but having recently played Control I think I've had my fill of FMVs of scientists in videogames excitedly videotaping themselves for a while.
Gris
A game about moving right, double jumping and collecting shinies the grieving process, going by the trophy descriptions (Denial, Anger, etc) and the store page blurb. Well, sure, you get that impression from the mournful soundtrack and all those sad statues. But like most artsy fartsy games, it refuses to commit to an actual story or a character, rendering it very pretty (love the hand-drawn enviroments and the splashy watercolor aesthetic) but emotionally bunk. If you remove all the enemies from a Mario game, cue violins and mute the colors, does that make it into a game about depression?
Untitled Goose Game
Great little comedy game about a goose who goes around pestering people who're too nice to do anything about it. It's in that Katamari Damacy/Donut County wavelength of cute teeny tiny cel shaded sandbox where you're given carte blanche to wreck shit up. The chaos is half fun, the other half is aggravating NPCs. You get a checklist of stuff to do (you're mostly trespassing and stealing shit) but no clear reason to do any of it, other than be a jerk. I'd say it does about as good a job at putting you in control of a "realistic" goose as Stray does when it comes to cats.
This was also the most involved trophy list of the lot, since you end up having to do tight 6 minute speedruns of each area to get the Platinum, which involves a lot of rng and uncooperative AI. To the game's credit I had just as much fun pulling these off.
