at the start of the game, players are put in a random location in the game world. they can begin breaking blocks to collect resources, such as wood and dirt, which can be used later in the game. players can use resources to make new tools, such as pickaxes, which let the player gather stone in the caves that they find. different resources require different tools to collect them. for example, diamonds can only be collected with an iron pickaxe, or one of a better quality.
