In all fairness, most of the problems you're describing are usually relegated to "polish", and there are still at least two more biomes to craft and integrate before the final polish pass.

This game is in Early Access; that means it's not finished yet. If that's not acceptable to you, then uninstall it and wait until it's completed to start playing. Whine about mechanics and UI then, or learn to give more constructive criticism than "I imagined this game as being more finished than it is."

Alternatively, create your own "Viking-themed survival builder" and show us the game we're missing. Oh, that takes time, skills, and money that you don't have?

Then be patient and wait for the finished product, like the rest of us.
Play what there is of it in the meantime... or don't.
