Map Info: Parkour between towers, through multiple biomes. Mostly above ground except for the swamp, and part of the ocean.
You will save automatically at each tower just by stepping inside of it, but you can also save at the diamond islands. When you fall, you will die and respawn at the last save point. However if you do get stuck somewhere just do /kill.
There are also 15 hidden chests with diamonds to find throughout the map, if you want to.
