When your createing your player for the game you can have the option to choose your terrain of your game.
Whatever terrain you choose you will need space, on the left of the image there is a open patch of tall grass, there is a great spot to put your crops cause of the less trees around it. Later on you can clear your farm from brush if you choose to do so. (This image is to give you a example or feeling of what would be a good place to set up crops).
Most people start making a chest on the first day, this is a smart choice to consider due to your lack of inventory space. As you can see it costs 50 wood therefore your gonna need to chop some trees. You will have more crafting options later on cause of the level up system but for now you are limited.
Level Up System
As you can see the level up system looks complex but it really is easy to understand. How it works is lets say your going mining, the more you mine the more you will level up your mining bar. Or the more you plant seeds you will level up your farming more, leveling up will make you craft more things for the specific catorgory.
