Also, if you forget anything Hugin told you, you can find it in the inventory screen (Tab on keyboard, Y on controller). On the top right of the screen is a box with four symbols:

• The raven allows you to see all the things Hugin has told you so far, as well as what buffs/debuffs are currently active on your character and what effect they have
  
• The intersecting triangles show you your current skill levels
  
• The pair of swords are for turning on/off PVP mode (which for this game means whether or not you allow other players to be able to harm you - straight swords is off, crossed swords is on).

Not in game right now, so I don't remember what the other remaining symbol is for...

Hugin will come back whenever you do something that he thinks you should know more about. You can punch small trees, and making noise while doing that will give you something else to punch. Eat food as soon as you get some so you have more health and can heal, but not eating won't kill you by itself.

Mostly he's annoying to people who have started over multiple times and already know all of his tips.

you don't have to punch trees, but you can.
there are tons of wood sticks on the ground that you just pick up, same for rocks and starter foods as well.

they tell you everything but a new game is
grab wood and stone
make a weapon (club will do)
make a crafting hammer (critical)
use crafting hammer to make a workbench and shelter
and from there crafting becomes a mix of the hammer and stations you install at your home. The hammer is mostly for building the home, the stations for most gear, food, and household stuff. Some need both the hammer and the stations, like iron+wood beams need a forge and the crafting hammer.

a full home needs about 50 square floor tiles of space (can be on several floors or a spread does not matter) Your first home is probably not going to grow to that, but its a good rough starting size.

the bird has about 15 or so total tips including "stop don't go" if you try to move on before beating the first boss. Most of them are pointless, and if you ignore him he keeps coming at you until you interact. The first 2 or 3 tips explain 99% of the whole game.

Hugin will come back when you accomplished certain things. He actually told you what to do in his first dialogue.

To make it easier on you, gather sticks and stones, anything edible and start crafting a stone axe, then the hammer. You can do this when pressing the "Tab" key. There's a menu on the right hand side on what you can craft.
