Thief Minigame

Thief, the Minigame
----------------------------
A Thief is on the loose in a small factory-town and guards have been sent to check it out.
It is said that the Tief is looking for 9 chests that contain blocks to build the mysterious beacon.
Why? So they can acquire the long lost art of haste, a power that all criminals admire for its cunningness and usefullness.

How it plays out
------------------------

Everyone starts in a room, 1 player is chosen to be the thief and the rest of the players are to be the guards.
The guards are armed with very strong equipment but the theif is armed with a selection of 2 tools, and invisibility.
The theif's invisibility will temporarily be taken away if they stand too close to a torch. The Thief can kill guards, who cannot spawn again and if the guard has an beacon-making block, the thief can take it.
