The first thing when you come the kingdom is to try to find fruit and food and then build yourself an ax or hoe and start exploiting other resources in the game.
When there is a certain amount of money from the sale of the resources you exploited, you will buy seeds and start planting crops and agricultural products. From here, you can proactively store and sell your products to get more money to upgrade your house or buy more machines to create other high-level materials in the game.
While building the garden, you will always be harassed by monsters. On the weekend there will be a day called "Blood moon" Monsters will appear and sabotage what you are trying to build on your farm. What you need to do is build guns to defend against aggressive monsters. In addition to the main gameplay, you are also experiencing mini puzzle gameplay. This will help you never get bored when playing Windykingdom.
