Self-promotion, since I'm the one who made it.

VonN starts you with a single von Neumann probe in a 10,000-star galaxy shared with other players. Light speed is the hard limit for everything. Your commands take 4 seconds per light-year to arrive, and what your ships see takes the same time to get back, so you're always working from old information.

It's free at https://VonN.io with no signup. I'm running the first real test right now and want to hear what space game fans make of it.

It's free, and it stays free. Cosmetics come from a Signal Cache you can open every 4 hours, and duplicates turn into shards. After the test, caches open with a short ad you pick to watch, and the end of a run plays one more. Paying $4.99 once turns ads off for good. Nothing is pay-to-win, and nothing is for sale right now.

I'm collecting feedback in the #vonn channel on my Discord. https://discord.gg/VzHpyQfV4q

Claude wrote some of the code, and I did the hard parts.

Hey everyone! Orbital Defense Idle is a sci-fi incremental tower defense game where tarot cards influence the fate of the battle!

I just launched my open playtest on Steam this week, its be really cool if you checked it out: https://store.steampowered.com/app/5027850/Orbital_Defense_Idle/

Thanks!

The game is inspired by EVE Online, but with three key changes:

• Less grinding, more strategy: Resources are regional, not everywhere. No single faction can mine or manufacture everything it needs. Survival depends on trade, alliances, and diplomacy, not repetitive mining runs.
• Building and community come first: Found a nation. Build a shelter even with limited resources. Claim and develop planets, down to small personal touches that make a place feel like home. The galaxy starts as an empty void, every station is built by players, from nothing.
• Other players stories are visible: See who’s in a system or station right now. Understand the supply chains that keep a faction alive, and who holds which role in it. Read what’s driving other players and use that for more complex diplomacy.

Hey everyone 👋

I'm the Community Manager for Kardaviik, an upcoming 3D factory automation game set in a voxel asteroid belt.

We're currently running a free, open playtest on Steam, and I'd love to invite the r/spacegames community to give it a go!

In Kardaviik, you can explore procedurally generated asteroids, mine resources and build sprawling factories across the asteroid belt. There's no need to stick to flat layouts either, as you can build in every direction and expand your operation however you like.

You can explore and build solo or team up with friends!

We're actively looking for player feedback, so whether you've got suggestions, run into bugs, or just want to show off something you've built, we'd really appreciate you getting involved!

👉 Join the Steam Playtest: https://store.steampowered.com/app/2385970/Kardaviik/

🎥 Watch the Trailer: https://www.youtube.com/watch?v=DEKiMgGg5kQ

Thanks for checking it out, and feel free to ask me anything about the game! 😊

Hi, I'm Justin, a space enthusiast making my first solo game, StellarForge.

I'm exploring spacecraft construction that begins with the machinery that makes the craft possible: a huge load-bearing spine and propulsion interfaces, with habitats built around them. Fighters would use compact chassis instead.

The images below are early Blender grayboxes, produced with AI-assisted Python modeling scripts—not in-game flight footage or finished ships. The proposed colony backbone is 200 metres long. This pass is about proportions, modular anchors and engine interfaces; materials, detailed systems and engine-side fit are still being worked on.

The wider game is a space colony-building project. Working systems and prototypes are at different stages, and the complete colony-to-spacecraft journey is not finished.

I'm looking for colony/space-game players interested in following early builds and helping spot confusing interactions and bugs. Join the Discord for development updates, feedback and test-build announcements: https://discord.gg/K3MUpZjD4

This is a tester-interest invitation, not a promise of immediate access. Honest criticism is welcome. Would you prefer building freely around an exposed core, or selecting a chassis with stronger constraints?

I develop World of Frontiers, a free browser space MMO. Our Halloween event, Echoes of the Void, opens October 19. This 30-second preview shows the Rift of the Damned, Dreadlord Nocturnus and a staged three-faction fight against the Harvester.

The seven-wave Rift has an earnable Specter cosmetic you keep permanently. October 31 is the Nightmare climax; November 1 remains open for farming and exchanging event currency. The event ends November 2, 2026 at 00:00 UTC.

The base game is playable now: https://florim-studios.itch.io/world-of-frontiers

Footage is recorded in our local game-engine event preview. Original synthesized score, synthetic narration and AI-assisted assets. Optional purchases.

Which encounter would you try first: the solo Rift or the shared boss?

I have published the first prototype of my game. It contains:

- 10 star systems

- 2 types of interstellar probe

- basic economy system

- resource manager mechanic.

Check it out on thegalaxiaboy.itch.io/fermi-idle

*AI usage explained in the game page

The old ones felt a bit empty and you could barely read the name on the small one.

Made the logo bigger and added one of the inspection ships you run into in-game. Wanted to show a bit more of the game itself. The ship model is by Quaternius.

The ship and planet use the game's current textures and lighting, so it does match how the game looks right now.

Old on the left, new on the right. Which would you click? Anything you'd keep from the old one?

VOID PROFIT on Steam:

https://store.steampowered.com/app/4687990/VOID_PROFIT/

I released the Steam demo for DeltaV today. I'm its developer.

It's a turn-based strategy game set in the Solar System. The part I wanted to build around is the fuel budget: every ship spends from the same reserve. A long transfer can leave you unable to defend a different ship, and holding a contested orbit burns through that reserve too.

Planets and moons move as turns pass. You can see every ship and order, including the enemy's, and preview the cost and arrival turn before committing a burn. The aim is to keep access to tritium while cutting off the other fleets.

The free demo is the guided tutorial, available for Windows and macOS. The trailer above shows the game.

https://store.steampowered.com/app/5070120/

If you give it a go, I'd like to hear where the tutorial loses you or which decisions feel unclear.

I develop World of Frontiers. This is the English 30-second cinematic: a look at Helios, Vesper and Ember, with animated 3D scenes and gameplay footage. It is a trailer, not an uncut gameplay recording.

The game is free to play on PC and mobile in a browser, with PvE, PvP, clans and optional purchases. Original music, synthetic narration and AI-assisted artwork.

Solo dev here. Space Defender: Frontier Squadron is a top-down space shooter with RPG progression, and the squadron is the heart of it.

You take contracts from stations on the frontier (escorts, convoys, sieges, hunts, rescues), earn credits, outfit your ship and recruit pilots who fly and fight beside you. You give them quick orders in the middle of a fight. A wingman who gets shot down ejects, and if you reach the escape pod in time, you get your pilot back.

In numbers:

- 13 ships, from the nimble Falcon to frigates and destroyers,

- 60+ modules: lasers, railguns, homing missiles, turrets, shields,

- 15 contract types,

- a story campaign in three acts across three galaxies, Act IV coming soon - for free

- Windows and Mac, controller or mouse + keyboard.

It just left Early Access, and there's a free demo on Steam.

AI disclosure: the character portraits and the voice-over were made with AI tools.

Question for you: in which space game did your wingmen actually feel useful? I'm collecting ideas for the next updates.

Hello! i would love some feedback on my trailer for a game i'm working on.

If you want to give me feedback on my steam page that's also appreciated: https://store.steampowered.com/app/5084070/Beyond_the_Belt/

Solarwind - Galactic Frontier I'm starting to build this and I want feedback. You orbit a real star, collect fuel called "solarwind" from it, and burn it to jump to stars reachable with collected fuel (limited to 8 ly in this test version). Every star is real: the colours, sizes and distances come from star catalogues. Flights are shown from the ship at near light speed: the sky crowds ahead of you, stars shift blue in front and red behind. Collecting continues in real time while you're away, and flights run in real time too, so it plays best in short visits. Initial goals are simple: reach Vega, orbit a giant, or get far enough that our Sun disappears. Eventually it will have player interaction with economy, diplomacy, war, exploration, NPCs... I call it "Solarwind - Galactic frontier". Feedback very welcome, especially what would make you come back and which parts of the bigger version you'd be interested in.

Hey space game enjoyers, this is my game - Asteroid Defense a game with real orbital mechanics like KSP mixed with retro arcade games like Missile Command and Asteroids. Any feedback would be appreciated!

Play it here: ad.stellarsoup.com

I develop World of Frontiers, a free browser space MMO for PC and mobile. Here is a short example of using a Glacier rocket to create a control window before firing the lasers.

Captured in the current build with a prepared pilot and enemy in a local test world, at normal speed; HUD hidden. Original music. Some assets use AI-assisted production. The game has optional purchases.

Play: https://florim-studios.itch.io/world-of-frontiers

What makes crowd-control effects readable for you in a busy space fight?

Yes! In this tiny universe, you steer your rocket by placing maneuver nodes (thank you, KSP!) and try not to run out of fuel before reaching your target.

Advance through a procedurally generated world, upgrade your spaceship with new equipment, and top up your tanks until you reach the final destination and crash into the sun (or whatever, I haven’t really thought about the "end game" yet).

The game is still in early development, but I would highly appreciate it if you'd check out my itch.io page: kdigital.itch.io/tiny-orbit

If you're into high-precision, physics-driven space games, leave a follow to keep an eye on the upcoming devlogs! I’d love to hear your thoughts on the mechanics.
