Rebels in the sky is a P2P multiplayer game about crews of space pirates roaming the galaxy to play basketball against each other. It's basically a basketball managerial game with some pirate-y stuff. It's a P2P game with no central server, built on top of libp2p. Players interaction are limited to playing games against each other and trading pirates. The game runs as a terminal application, meaning that you just need to run it from your terminal. You can try the game over ssh without installing: `ssh frittura.org -p 3788` My server is not very powerful and there is a limit to the number of…

Hi HN! I'm working on an open-world multiplayer space sim with submarine-warfare-inspired combat. Crew a ship, haul cargo, run heists, hunt your foes with passive and active sensors. Browser-based, free, no install. Some of its features: - Submarine-style passive sensors. Contacts start as a bearing line (direction, no distance), resolve into an uncertainty circle, then into a full track. You triangulate over time by moving. - Silent running. Cut your emissions and witnesses can't ID you. - Newtonian flight. No drag, no auto-brake. Flip 180° and burn to stop. - Boarding combat. Dock with…

I built a desktop Mars colony survival game called Underhill, in homage to Kim Stanley Robinson's Mars trilogy. Land on Mars, build solar panels and greenhouses, and try not to pass out during dust storms. Eventually your colonists split into factions: Greens who want to terraform and Reds who want to preserve Mars. There’s Chill Mode for players that just want to build & hang, and Conflict Mode that introduces the Red v. Green factions. Reds sabotage, the terrain slowly turns green as the world gets more terraformed. Feedback welcome, especially on performance and gameplay!

I built this with Claude cause I always wanted to tinker with a simulation economoy and I love space themes. A space-economy sim where nothing is scripted. A few hundred autonomous ships each run their own planner. Some chase the best trade route, take a delivery contract, refuel, retrofit at a shipyard, or dock so the crew can rest before morale tanks. Markets price everything off supply with shortage-urgency multipliers, factions tax and subsidize, populations migrate when they're unhappy, and stations that go broke get abandoned and rot. It started as an Elixir/Phoenix prototype, but…

After losing my job, I decided to channel my energy into creating my own sci-fi adventure game. While I’ve previously released a VR game, I’ve been working as a regular software developer for the past few years. The game, Star Mission: Remote Sectors, is a first-person exploration and survival experience set on an uncharted alien planet. Players use superhuman abilities like telekinesis to uncover anomalies, navigate environmental hazards, and survive in hostile conditions. A big inspiration for the game was classic sci-fi movies and the optimistic vision of Star Trek. The journey has been…
