This is a minigame that is half skydiving and half PVP. You need 2+ players for this game. There is a button that gives you a kit. After this, pick your character. You'll be teleported 10,000 blocks in the air. Beat your opponent before you hit the ground!
It you like this, can you give me a diamond? I used 15 command blocks, about 50 repeaters, and 150 pieces of redstone, with 8 pistons. This map took 3 days to build.
