Survival Mode

In Survival you must gather resources to build what you want, craft, and battle monsters because you have a health bar. Survival mode also has of smaller "sub-modes", which are Peaceful and Normal. Normal mode has hostile mobs and only food will heal you, Peaceful mode has no hostile mobs and your health bar regenerates slowly over time. More modes are expected to be added in future updates.

Health Bar
The main feature of this mode is the appearance of the health bar. This means that you take damage from falling (Half a heart per block, after the first three blocks), being attacked by Hostile mobs, drowning or suffocation (meaning you're stuck in a block).

Mining
The other most recognizable feature is the lack of unlimited blocks and that there is no instant mining. Rather, in survival mode the blocks must be hit with one of the Tools or a Hand. When starting the mode the player has no items. So, the player must start punching trees, mining, and get everything the player wants to build to create the structure they dream of.

Crafting
To create the tools the player (You) will have to craft items Crafting item lists can be found on the following pages:
 * Food
 * Block recipes
 * Weapons recipes
 * Armor

Mobs
Survival Mode also introduces hostile mobs such as,


 * Zombies


 * Skeletons


 * Creepers


 * Spiders


 * Zombie Pigmen
 * Slimes

All these mobs do damage. You can use a sword to do more damage to them. They are easy to defeat, but when there is a lot of hostile mobs, it may be hard to handle. Slimes, Silverfish and Enderman were added in Update 0.9.0.
 * Enderman

Farming
You can turn the grass to a farmland block by using a hoe and if it's near water, it will turn hydrate. You can place the following blocks: The act of eating restores hearts the amount depends on the item. The melon is the only item that can be eaten from scratch.
