Fallen Blocks is a 1.8 parkour map featuring the story of a hero, you, the player, who is the only survivor of a corruption which has scrambled Minecraft's code. The only thing the hero can do in order to restore Minecraft is jump.
This map overall is difficult, however, completely possible. As you progress along levels, difficulty will steadily increase and you will discover Minecraft isn't quite the exact same Minecraft it was before with certain blocks giving certain effects. As time progresses, the coding will begin to debug.
Fallen Blocks is playable with any amount of players. Recommended 1 to 4.
