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!

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.
