However, once I figured out a wooden shack with a door built in a couple of minutes completely thwarts the AI enemies, I lost most interest. The setup is player against the world, but the world doesn't know how to do anything you'd need a huge stone castle or a massive trapped dungeon to fight against, so the great build system feels a bit pointless now.
Got to hand it to the author for making excellent core mechanics from a very simple set of ingredients. I hope he can keep up working on the style and figure out enemy mechanics you actually need serious constructions to fight against.
