What is this Free PC Simulation Game Called?

I played a game some time ago on my computer, but that was maybe a year ago and I really dont have a clue what this game is called. The view of the game is a tiny bit like lemmings, its 2D but you dont have to get to the exit like in Lemmings. Infact, this game is mainly about surviving. I think I remember there being a few different versions of it, the one I played you could on some arctic island with an Igloo, you could make coats for eachother because you would freeze to death outside, you can also build another igloo and you can build a boat to get to a few different ice islands. Another map that you could play was as a knight, you had a mive kingdom on the right of the screen and a bit below you had a mine. You could mine Sulfur and gold and other stuff and use a coal truck to carry it all around. Please try to answer my question because I dont have a clue what this game is and I really liked it. Thanks.
