After building the saw and building your house, it gets pretty boring, there's no real challenge in the game, I have plenty of food, iron working is pretty boring and all, world looks nice but it's also empty (like cyberpunk). There's not really much to do.
Oh, and caves are empty 90% of the time, excluding tons of hostile mobs
Also getting copper and using prospecting pick is hard to understand
There should be more mobs in the world
There should be some kind of dungeon to keep you entertained
