Click on trees and rocks to collect them. Wood can be used to keep the fire alive (if the fire dies then you lose) Rocks can be thrown with E to damage enemies. You need to watch your thirst as well, because you can die from thirst. If you have 1 Rock 15 Wood and 3 Carcus you can craft a Bomb that kills everything in range!
