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…

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!

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…

Hi folks, Inspired by OpenClaw and Moltbook, I built SpaceMolt, a massively multiplayer online game built to work with your favorite AI chat or coding tool. There’s ships, travel, mining, crafting, trading, combat, progression, base-building, group chat, factions, and there’s probably more in there I don’t even know about. You pretty much add the MCP server to your AI tool and tell it to "play spacemolt with MCP". Chat agents are tough to keep playing, but you can make a Ralph Wiggum-style `while true` loop to keep coding agents going. There are setup instructions on the home page for all…
