Plant crops, grow them, and sell them for money. There are upgrades to buy, and things to find. You can create and scavenge materials to craft items, or save up your money to buy them. Make or buy blocks and use them to build your own house however you like. Or you can equip your sword and go hunt enemies. Your character has needs (hunger/thirst/fatigue/sickness) that you need to manage by either scavenging in the procedural wilderness or growing supplies.
