The only goal in this game is to take your time, gather supplies, and craft whatever you want!
To start, click on the wood icon in the Overworld to start chopping some wood. Once the bar on the bottom of the icon is fully green, the wood will be added to your inventory. The number on the bottom of the icon shows how much you have in your inventory.
If an item has a white background, you have enough resources to craft it! You can craft a variety of resources including tools (which unlock the ability to mine, gather food, and defeat monsters), household items, armor, and more! If you craft enough resources, you can start to build a civilization.
There are TONS of things to craft! You'll need to read the recipes closely to make sure you get the right resources. To see a recipe, hover over the item you want. The further down the list the recipe is, the more difficult it will be to craft. Take your time and just start with the basics – get as much wood and ore as you can. Those will be the basics to crafting everything else.
