Hey, you can read the signs for a basic info.
Basically you press tab to open the Inventory, you can click on item to equip them.
You can plant trees and they will grow, every ~10 minutes a random tree ignites, if it fully burns the fire spreads to another tree and so on.
you can buy a fire extinguisher to extinguish them.
Theres a shop when you go through the bus with the e key and enter the house on the left with the e key.
For some reason the transition animation doesnt play in the final build but you can get earlier builds on:
