Unstable on windows. Can't see the edge of a map without extreme lag. No menu. Mouse is always visible. Sticks just sit there after their own "fire" has gone out. No jump button while you're holding sticks.
Would be cool if I could build stuff to allow me to cut down trees.
Right now, the only thing to do is to move around and pick up things to bring them back to a central location for no purpose to the player.
