Stationeers. It's a game about managing a station on another planet. You have to manage things like the atmosphere composition and pressure, as well as temperature, while growing plants and mining/smelting metal. It's a really cool game, with the refrigeration cycle actually functioning so you can build your own heatpumps.

It's made by the team making Kitten Space Agency, which they want to give away for free. Last I heard, they're losing money developing Stationeers too, but they're fine with that and continuing anyway. The owner of the studio is the person who made the DayZ mod, and I guess he's got plenty of money now and just likes making games they're passionate about.

Slayblade! It's not out yet but I did enjoy the demo.

Hmm, this is far less obscure than some of the other comments, but very much indie at the same time:

Enderal

This is technically a mod, but is in Steam as its own game (vs in the Steam Workshop) bc it's a legit full game; they broke Sktrim down to its assets and rebuilt a completely new game out of it. So, familiar mechanics and engine; brand new everything else (lore, terrain, voice acting, music, etc).

It's a passion project from an indie dev crew iirc based in Germany, called SureAI - note that they've been around since 2003, and have no connection to the the slop we're calling "AI" nowadays.

Enderal is a 90-10 slit of absolute masterpiece and absolute jank - it's Skyrim's engine, so it has all of Skyrim's problems. You WILL run into stupid shit like quest items falling through the floor, so save frequently (real save, that makes backups, not just quick) and don't be afraid to fix shit with console commands; but once you get past the Skyrim jank, you'll be treated with an absolutely incredible story that delves into philosophical and emotional topics. You know that sunken feeling you get when you finish a really good book cuz you CRAVE more, but know it's over? Enderal is the only videogame that's ever evoked that from me. Cannot overstate how damn good the writing is!

Actually playing it... it's been a while, so it might be different now, but last I played it required you to have either the original release or special edition version of Skyrim already in your Steam Library, enabling it to hijack the assets. So, whichever one you have, download the corresponding version of Enderal. The plus side is that it's completely free barring the Skyrim requirement - and like, actual free, with no ads or micros or any of that BS.

If you have both, DL the version that you don't usually play in Skyrim - this will enable you to have both installed at the same time if desired, with no fuckery from competing file use. ...if just one version, back up your Skyrim saves before installing, as it's been known to cause issues.

Anyway, remember that first playthrough of Skyrim when everything was brand new and you didn't know the game like the back of your hand? ...this is the closest you'll get to revisiting that experience. Possibly surpassing, since Skyrim's story is kinda cliche; Enderal will make you feel something new.

One pseudo spoiler: they redid combat and leveling mechanics. Don't lean too heavily on the tricks you know from Skyrim. Aka, sneaky archer will get your ass handed to you. Experiment with the different combat options! Avoid additional spoilers like the plague.

In Other Waters - a fairly unique exploration adventure with timed-puzzle elements and survival mechanics. The graphics are very stylised, so the experience is more like reading a book. I played about 5 hours and mostly enjoyed it, but did not finish it because the survival/timing pressure got too stressful as I progressed through the story.

Try out Distance, a race game where you have to dodge objects. It also features a great soundtrack.

Diaries of a Spaceport Janitor

You play as a poverty-level janitor at a bustling space port. Scrounge by while longing for a better life, seeing wonderous things that are beyond your class/wage level to experience! It sounds depressing, but this is a very charming game.

Smushi Come Home

Cozy 3D platformer with no combat and tons of chill little dudes to talk to and help out.

PictoQuest

Nonogram RPG. The story is nonexistent and the dialogue is laughably bad, but this is one of the better picross games I've played because the puzzles do actually look like stuff, and the completed puzzles even have animation! Plus the added elememt of combat gives puzzle solving a fresh twist.

Gunz: The Duel is planning a comeback some time this year; tl;dr extremely niche 2005 korean team/solo shooter famous for the playerbase essentially creating a hyper-mobile fighting game but with guns out of the incredibly glitchy but consistently glitchy movement and animation system. If you've never played it it has a huge skill barrier to entry (that I'm sure will be tutorialized in this modern reboot) but is incredibly fun and satisfying with a huge skill ceiling.

Rabbit and steel

unfortunately, blahaj.zone doesnt have downvotes

Duskers!

A sci-fi/horror game where you try to survive the vast coldness of space by controlling a group of drones through CLI or individual ones via top-down camera.

Pretty interesting, deep lore and quite atmospheric.

It's both on Steam & GOG.

Grip: Combat Racing. Insanely fast. Crazy tracks. Weapons! I haven't tried it in VR yet, because YIKES!
