Why do I see my hands? Can I punch?

When the hotbar slot you selected is empty, or the item in it can't be used (for example, a broken weapon or wood), you now see your hands and can punch. Punches hurt players and animals but don't damage buildings and don't gather resources.

Weapons in first person also move more naturally now: they sway when you start running, stop, jump and land. When you aim, the weapon stays steady.
