I went a bought it, and going to get a copy for my gf, she loves this game.
So far I made myself a good shelter, made some shoes, and pants and continue to gather resources and look for caves.
Sometimes though I have no idea what I picked up, the rocks for example. I know what the regular rock looks like, but there are other ones that are just a little different in color or texture and I have no damn clue what they are.
I try to smelt them in the furnace no luck, try to make some tools out of them and no luck. I guess it is just trail and error...
This game is addicting though, so simple, yet so deep and so much fun.
