It's free to play on steam, but you'll need a computer with a dedicated graphics card. I just released a new version after first releasing it 18 months ago. It's been a hard slog to scrounge time as it's not my day job but that's life. There's a ton of obvious improvements in the future (weather systems, temperature, varying rainfall, ice/snow, more biomes, more plate tectonics, lava, etc) but all suggestions/feedback is welcome.

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!

My cousin and I love the Terraforming Mars board game. But we'd often get overly excited and knock our pieces off of our boards, losing track of our progress. So I digitised it. It comes with a few cool features like resource conversions (e.g. converting plants to greenery), production phase, offline, mobile-friendly and keeps track of the history using the browser history itself. Sharing this here in case there are any other TM fans that could also find some use in this :)

I made a game (https://polyfight.io/) which revolves around a player (a tank) leveling up and upgrading by killing shapes and other tanks (partially inspired by https://diep.io). It has a bunch of features, a vast number of tanks, an inbuilt chatting system, clans to make teams with your friends, a colour scheme maker, controllable sandboxes which can be public or private, a last man standing gamemode, and an inbuilt 1v1 system with its own ELO rankings and a global leaderboard. The game has a few players right now, and I'd hope to spread the joy players have with…

Hello guys, I'm glad to present to you PlayAlgoShip, a web-based game where you solve fun algorithmic puzzles. The rules are simple, you need to find the correct algorithm that makes the ship collect all stars. If you succeed, you will unlock the next level! There are also live statistics like how many players are currently playing on your current level (you are not alone struggling!), the finish rate of the level, and how many players liked/disliked it. It's 100% free, I hope you will enjoy the experience!

Hi HN, I'm a solo dev working on a space RTS game set in the Milky Way galaxy, containing currently known stars and exoplanets with their real characteristics, the remaining stars are procedurally generated. In the online mode, all players are in the same universe, and the world is persistent. You compete with other players to take back the Solar System and end your exile. Players can always retreat to the periphery to regain strength and rebuild their fleets as needed. It also includes an procedural spaceship generator that allows creating your own spaceship designs. Spaceships visuals…
