You can't. You can play other games like it. But not minecraft.
Try playing Blockland. It's a game similar to Minecraft. There is even a free trial version.
there is no "contract" in minecraft like in RPGs like runescape membership. minecraft is a 1 off payment, around £15 i think. after which it is fully updateable and will never cost you anything again.
Minecraft's bats do not eat anything. You can't feed them anything nor do they look for any other kind of food.
You can get a mod to do just about ANYthing you want, just do a Yahoo/Google search for something like "minecraft mod".
Literally anything physically possible in Minecraft.
Minecraft does not ship anything to you unless you buy merch.
Anything you want.
You can build anything ! but the best will be to build a auto smelter, Here is a link to the tutorial....
There is no command block in minecraft. If you go to the Minecraft WiKi it will have all the information you need for anything in the game.

Minecraft beta is not free, you have to pay to play it. Any website attempting to give you Minecraft for free is illegal. If you find a site like this do not download anything from it as it is not only illegal, but may contain viruses.
