My game has been finally released and is available to buy on Steam store
I think it is worth to mention that game supports Steam achievements and cloud. I have in my plans to setup Workshop so players can share in the future with additional content (like maps, miner's races etc) that they will create.
There is also a demo available there, if you haven't a chance to try it earlier.
Hope, you will like it! Please feel free to share your thoughts about it here in comments, on Steam or by sending me an email.
