You are but a man with a spear, and with that, you can conquer the world. Or at least your island. Losts.io is a land-conquering game with plenty of progress and unlocks.

Your character will follow your mouse, drawing a line whenever you leave the safety of your territory. When you return back to your territory, you claim more space. But if someone hits your line, you die.

You can stay close to your territory and expand slowly without much risk of dying.
