The lost castaway, you must do only one thing, survive at all costs, there is no iron, nor diamond, there is only water and wood, how long can you survive before hunger or one of the creatures that inhabit the depths of the sea kills you , do not try to escape because surely you will not be able to and even if you try you will not get very far, search the island and maybe you will be lucky to find something, but if not your only salvation will be food rationing and a good strategy.
