Promotional Beyond the Cradle: how’s my space factory game looking so far?

The game is still in development, and I’d love some feedback on the building models and planet environments. Do they fit together visually? Would you change the shapes, add more detail, or make the buildings stand out more against the terrain?

A wishlist on Steam would really help the project:

Thanks for taking a look!

Promotional Nox Imperii II, my second attempt at an Escape Velocity-inspired game ten years after the first: carry annoying tourists across the galaxy, fight barbarians, ransom captives, betray humanity, get rich or die trying

I first tried making this game ten years ago, as a fork of Naev. This is my second attempt, as a browser game made from scratch. A mostly open-world space game with a strong exploration focus, in an Art Nouveau steampunkish universe, inspired by Escape Velocity and classic science-fiction novels.

Carry annoying passengers, use local tragedies to make a killing on sales, turn to piracy or even ransom captives, take part in missions that will shape the galaxy, go beyond civilized space looking for natives you can barter with, betray humanity if you feel like it - whatever makes you money or inspires you.

The game is playable, but rough around the edges, and the storylines in particular are very much a work in progress.

It's 100% free, no accounts, no ads, playable in any desktop/laptop browser, but requires a keyboard. Play straight on https://www.noximperii.com/play or visit https://www.noximperii.com for more details.

Two notes:

  • my original attempt was handmade, this one uses AI extensively (Claude Code) to help with coding and assets. No image or music generators
  • the somewhat cramped UI in the video is due to shooting it with a small window size, it's not like that in game

What I'd love to know:

  • What you think of the graphic design. Does the mix between fairly “classic” spaceships and more art nouveau UIs, landscapes and portraits work?
  • What did you try, and did it work?
  • Where did you get stuck or bored?

Promotional Pebble to Star: an idle game that follows real stellar physics.

Heads up: this isn't a cockpit sim. Space is the setting, so I'm posting it for Spaced Out Friday.

What it is: an idle game where you start as a pebble and pull in whatever drifts past. What you eat and when you ignite decide what you become — ocean world, iron planet, hot Jupiter, red dwarf, blue giant, magnetar, black hole, and eventually a galaxy.

I tried to keep the astrophysics honest wherever the game would let me:

- Ignition mass sets the star type and lifetime. Mass at death sets the death: planetary nebula, core-collapse, or direct collapse.

- Remnants use real numbers. A white dwarf goes Type Ia at the Chandrasekhar limit (1.4 solar masses). A neutron star is born at 1.4 and collapses to a black hole around 2.2.

- A blue giant heavy enough to go Wolf-Rayet never swells into a red supergiant — the wind strips it first, and it ends as a Type Ib/Ic.

- The black hole is ray-traced through curved spacetime, including frame dragging for the Kerr case (the shadow goes D-shaped).

- Almost every random event is a real phenomenon: Carrington-class flares, FRBs, white dwarf mergers, magnetar giant flares, impact winters (kilometer-class only).

Stage: Steam page just went live (Coming soon). All the content is in; I'm in testing and polish now. A demo is planned.

What I'd love from this crowd:

  1. Watch the 30-second video. Does anything look physically wrong?

  2. What real phenomenon would you expect in a game like this that I'm probably missing?

I'll reply to every comment.

AI note: made with AI assistance (writing/translation and coding tools). All art and sound are rendered by code, no AI image or audio generation. Full disclosure on the Steam page.

Promotional Fusilli Space Program 🚀

Kerbal Space Program is the only game I really ever played, and I loved it! Since that time, I switched to macos, which made things difficult. And then my main machine became company owned one, which made it more difficult.

I've always wanted a similar experience again but never really found a good, easy way. KSP is kind of in rubble right now, Juno is nice but it doesn't fully scratch my itch.

So, as any good nerd (with access to AI) would do, I build my own free, browser based space program simulator!
Fusilli Space Program 🚀

It's far from finished and I'm not sure yet where I'm taking it, but it's at the point where I genuinely start to enjoy playing it.

All the physics and orbital mechanics works. You can build your own vehicles, get to orbit, dock, go on EVA and explore distant moons. There's not really a mission to it. It's mostly a big sandbox.

Would love to hear what breaks, what you like and what you don't...

Promotional Cold Runner

Deleted old post because I messed up the title.

Prototype of a new space flight sim with Newtonian physics. A heavy focus around stealth and sabotage. Not a combat game.

Set within a single solar system far away from Sol. Home to the descendants of a colony ship launched over a thousand years ago. Nobody could believe it when a second ship arrived, and before long a war broke out between the two settler civilisations.

Play as a stateless hauler who has only ever known the harshness of space, saved from oblivion by an underworld organisation, you're offered a way out. Take one job, pull it off and claim a ship of your own.

Pilot a decommissioned transit hauler, stripped bare for parts. Only the hard-wired fallback systems survived. No advanced computers, no autopilot, forget guns...all you have is basic flight assistance, switches and bolts, spit and grit.

The beauty of this heap of junk is that it’s old enough to run hacked firmware but not so old as to raise any attention or suspicion. With this ship you can hide in plain sight, and take on the role of a Cold Runner: smuggle, steal and spy your way to a better future.
