Ghost Hunters

Its a small game i made when i was bored. This game is called Ghost Hunters. What is the game about? The game is like Ghost Craft but its all redstone and there is no plugins or anything needed just pure vanilla. Make sure to allow command blocks to play. The game will choose a random person to be the ghost. he will have 15 seconds in a glass cage before he spawns in the map. In those 15 seconds people need to run and hide. The people need to kill the ghost before it kills them. Hope you have Fun!
