It is a small team and they work very slow. As of right now they are actively working on the next large update.

The parts of the game that has released feels complete so surviving in a Viking world progressing from meadows - forest - mountain - plains is very satisfying and you will definitely get you moneys worth. Especially if you like survival base building.

However right now there is no end, you just stop progressing so on a play through you will eventually go "well, guess I'm done" no true ending. To me that's fine as there is no great story here anyway.

If you are concerned that they may not finish the game. They might not, it is early access and thus no guarantees. But Coffee Stain is the publisher and with their name attached I doubt that it would just be abandoned.
