Rabbit and Steel - Cross between a bullet hell and roguelite with raid style gameplay. Requires very close co-ordination with your team to survive (up to 4 player co-op). Punishing but rewarding.

Hidden and Dangerous

Only H&D2 is on steam

The original was fantastic and v2 built on that. Fantastic 3rd person WW2 tactical shooter. Haven't seen anything like it in over 20 years since.

Veloren

Veloren is an action-adventure role-playing game set in a vast fantasy world.

Severed Steel is a single-player FPS featuring a fluid stunt system, destructible voxel environments, loads of bullet time, and a unique one-armed protagonist. It's you, your trigger finger, and a steel-toed boot against a superstructure full of bad guys. Chain together wall runs, dives, flips, and slides to take every last enemy down.

Magium

Not a pc game but rather on mobile. It's a really solid fantasy CYOA game and (if you wanted to) play through the next set of story chapters completely for free as long as you meet the achievement requirements. Barring that, buying books (as the game calls it) has a rather fair price. Unfortunately the game is incomplete as the solo developer has sadly passed away, but what is here is great with a decent length since there's been years of book chapters. Genuinely a hidden gem that I discovered on a whim back early in highschool, and it's sad that I won't be able to see the end they envisioned, so with that in mind I'll be replaying this game again in the near future.

Maize, a point and click/walking simulator/puzzle game about a secret military project to create sentient corn. Quite possibly the silliest game I've ever played.

Enderal: Forgotten Stories

It is actually a Skyrim mod but basically a complete game that just happens to be built upon Skyrim. It features full professional quality voice acting in German and English, new game systems inspired by the Gothic series, a setting separate from Elder Scrolls, and a story that gets close to the quality of Planescape Torment or Disco Elysium. I can't recommend it enough.

Azimuth

Azimuth is a metroidvania game, and something of an homage to the previous greats of the genre (Super Metroid in particular). You will need to pilot your ship, explore the inside of the planet, fight enemies, overcome obstacles, and uncover the storyline piece by piece. Azimuth features a huge game world to explore, lots of little puzzles to solve, dozens of weapons and upgrades to find and use, and a wide variety of enemies and bosses to tangle with.

It is open source and available for Windows, macOS, and Linux.

AAAAXY. AAAAXY is a nonlinear 2D puzzle platformer taking place in impossible spaces. You can take a walk on a Möbius strip, try to find the platform with your train at the train station, and play a piano that makes the Shepard tone. It will be a bit confusing at first, but I promise it will eventually get fun.

It's not on Steam, but it's available for download on the website for free. Linux, Windows, macOS, Android, and iOS. Also on F-Droid and FlatHub. give it a try im begging you

Tinykin
I know you said less than 1,000 reviews but this is at 1,500 so I think it just squeaks by.

This game for lack of a better description, adorable and over too soon.

Like a mashup of pikmim, Spyro 2, and Tony Hawk Pro Skater. It's got lots of fun platforming and new puzzle mechanics in an ever adding open world that is a true joy to traverse and cute silly little side plots that make for rather grand set pieces when it all comes together. I got 100% in 12 hours but also collect-a-thons are my jam and I was plowing through the game with grin on my face for everything but the platinum time trials.

Tin Can

Tin Can is a space survival simulator, where you are trapped in an escape pod after the loss of your ship. There are a few systems in your escape pod, and each system has components you need to look after. Your pod regularly flies through astoroid fields & other space phenomena that break these component parts forcing you to repair, replace or do without the systems keeping you afloat.

The Last Sovereign (NSFW) is an 18+ RPGmaker game. The basic premise is this: What if you had a setting with a bunch of hentai tropes lumped together and played straight, with no porn logic or stupid characters?

You play as a middle aged, very competent army veteran who gains the powers of an incubus, and reluctantly uses them with the aim of making the world a better place, slowly developing a harem of well realized, cool characters along the way. There's sex scenes, obviously, but you very quickly forget all about them as you are plunged into an underdog story where you have to manage your fledgling armies + resources and have to constantly make tough decisions.

I you love puzzle games you need to try Can of Wormholes, over 100 handcrafted puzzle stages where every puzzle introduces a new idea or interaction, very underrated game.

13 Sentinels: Aegis Rim

Sadly, it's not available on PC, but it is available on Nintendo Switch (US eShop page linked above) and PlayStation 4 (and PlayStation 5 through backwards compatibility).

It's a sci-fi game made by the creators of some games you might've heard of in passing (namely Dragon's Crown, Odin Sphere, Muramasa: The Demon Blade, etc.), Vanillaware. I can't go into any details about the game itself because of spoilers, but I will say it is quite simply the best and most uniquely told story I have ever seen in a game. It's a game you have to experience for yourself. You should go into it as blind as possible, too.

I will say the English dub of the game is also surprisingly good, considering it was recorded almost entirely in COVID lockdown. The Atlus West sound engineers (Atlus published the game in the west) must've worked some incredible magic to get it to sound as good as it does.

I genuinely have NO clue if this game is known, but i suspect it mostly isn't.

It's Keyboard Drumset Fucking Werewolf! It's kinda like a music video, but it's a music video game 👉😏

It's a collaboration between 2000s indie weirdo darling gamedev cactus and Swedish synthpunk band Fucking Werewolf ASSO.

it's aggressively strange and moderately challenging, but I think it's just a goddamn delight and maybe you will too.

Twinsen's Little Big Adventure 2 Classic (aka LBA2 or Twinsen's Adventure)

You are Twinsen, a little tank-like controlled character that's about to go on an adventure to save his planet!

The tank controls may be getting a bit used to, but you can jump, roll to the side, hop backwards, etc, so you can apply some creativity to your movement. Shout out to the Magicball Network for staying alive all those years!

Go out there, meet a godess, defeat a dictator!

Metal Fatigue

A fun little 2000 era RTS with customisable mech chassis units/base building/multiple fighting levels per map (separate air/land/underground maps). In hindsight, it has a fiendishly difficult campaign which I remember it being a lot easier than I find it now...

CONCLUSE

Concluse is an atmospheric horror game which features puzzles, outstanding cutscenes, and something a little twisted..

This one is free! Unfortunately a lot of my niche games are horror, not sure how broad of an appeal that is, but hopefully there's some horror fans here :^)

Voices of the Void a free (likely while it's in pre-alpha) light simulational game about receiving outer space signals and recording them to sell. You use the currency to clean up, upgrade, and decorate your small facility while moving around the Swiss forest valley you're in to repair and upkeep the satellite dishes that make the operation function.

It sounds very purely simulational, but there are a lot of secrets and interesting signals that are more than signals. It's also an Unreal engine game, but features a lot of Source engine love, for example the art style is reminiscent of Half-Life 1, all of the sound effects are EXTREMELY Source game nostalgic, and there's crouch jumping.

Out of Space a cozy co-op game similar to Overcooked but less chaotic.

Severed Steel. F.E.A.R. meets Tron, plus a Mega Man arm cannon, plus the movement out of Titanfall. It's incredibly fun and satisfying to play, and it has an exceptional soundtrack (if you like synth).

Vangers is a postapocalyptic and fundamentally strange top-down driving/exploration/mystery/action-RPG.

It has a unique back story, hostile worlds and an intriguing and expansive vocabulary that helps tell the story. If you are the type of person that appreciates poetic neologisms because they get your brain going, guessing at the etymology and sucking up the layers of connotation, this is up your alley.

Even if you manage to complete the game, you'll be left wondering whether what happened was even meant to happen. It's sort of post modern with deconstructed words, rituals and behaviors all jumbled up and muddled together as a result of a great and important event that once had meaning to creatures that may no longer even exist.

Heaven's Vault is a game about archaeology and translating a dead language. You explore a unique solar system and discover ruins, in which you uncover artifacts, and bits of text. Through context clues, you translate the passages to uncover the storyline. It's not difficult, so if you're looking for a puzzle, this won't really do it for you, but it's more of a narrative experience. If you aren't sure about a word or phrase, you can give it a guess (based on assigning words from a collection of possible translations to specific symbols), and the game will remember that choice and let you slowly revise your translations as you find new text that rules out prior incorrect guesses. There's an interconnected storyline with multiple paths to follow, and a very unique world - haven't seen anything like it in other games.

The game has a NG+ mode wherein you start with all of your translations from the first playthrough intact, but, most of the bits of text are considerably longer and more involved, letting you use your prior knowledge to uncover more of the story and the lore of the world, which is also neat.

It's a Block Pushing Game is a sokobanlike from the creator of Baba Is You. It's relatively short but has multiple novel mechanics. I enjoyed it enough to create a curses client for it.

PS: If you like Baba Is You, Hempuli publishes multiple new games per month, mostly clever sokoban-likes, at https://hempuli.itch.io/

To me, Ctrl Alt Ego is not well known enough. It is an immersive sim in the style of Prey. You play as a robot roaming a station, where your Ego (like a spirit) can pass into and control all sorts of objects to solve puzzles, evade, control or kill enemies. The graphics aren't impressive (it was made by a 2-person team) but the gameplay is so interesting and the story is surprisingly compelling and funny!
