Additions
New mob the Balloon, with its own dorp the balloon leather.
Added a new item the amulet (attack damage 6) with a fast "break", which allows the player to fly in a limited way in survival, gives a regeneration of 4 and an extra row of hearts all this only if the player is shifted.
Added an altar that allows you to recharge the amulet with the balloon leather.
Added a new trade that will get the balloon leather.
Now if you put the balloon leather on the camfire it will become normal leather.
Changes
Revised the spawns of the old structures of the birch forest biome that will now be rarer.
Revised some trades with the villagers.
This is just the first part of this update, in the next versions a lot of other features, blocks, structures, music discs and many other things will be added. While the things not obtainable in survival in this update like the amulet will be made available in the next one.
