Now released as open source
- As the developer for this game has shut down, we've decided to release it as free to play and also open source under a very permissive license. We hope you enjoy!
The game works on Steam Deck, in fact we believe it should qualify for full compatibility, however we are waiting on Valve for an official Steam Deck compatibility review.

What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Players generally enjoy the game's core concept and find it engaging once they learn the mechanics, praising its fun factor and potential. Common complaints include confusing UI and tutorial clarity, occasional AI inefficiencies with task management, and requests for better modding support or workshop features.
Its a bit glitchy in startup and quitting. Have to force quit every time because it just hangs. Has an error for saving the game fairly often and flashes a message on screen. From that point on it wont save and you need to reload the game. The last time this happened, it completely deleted my save game directory and file somehow. I lost 30 hours of gameplay and really dont want to start again.
The tutorial is basically useless tok me 4 colonies that starved to get something that works and after 18 hours I would say I know most things but the game always finds new ways to screw me over. The game is good like really good. It has mechanics I won't spoil for anyone new but things you definitely wouldn't expect at first. Overall I'm having a great time playing it. Having small lag during winter on a medium map and max speed and max zoom out but its not much.
theres a bug where the ppl wont construct buildings but it only showed up two times so ether than that its fun top down dwarf city builder you can mine into the mountain and make buildings.
i know ive only had 6 hours on this game so far but im really enjoying it i always loved watching videos of rimworld and games like this where you grow your colony and i could never run rimworld this is laggy but a free awesome alternative so yeah you should try it out
Its grate in my oppinion wish there was a workshop for modding to be honest
is grate
