You lead a small tribe of hunter-gatherers, and your goal is to gather enough supplies so that your people could travel across the mountains to more bountiful lands. You get resources by killing animals and gathering resources from the environment, but you also consume resoures slowly over time.
You win the game if your gather all the required resources, and lose if all your hunters and gatherers are killed.
You have two types of tribe members you can control, and the Shaman. The Hunters are good at hunting, and the Gatherers excel at gathering. If one of your tribe members gets wounded, bring her to the Shaman for healing (there's a cooldown between heals).
Click a tribe member to select her, then click where you want her to go.
