Just a world where there is a easy and simple version of bunch of working portals that will teleport you to location you want.

A simple Piston Sawmill.

its kinda a test to see the village explode, by the way you have to replace the button with a lever first! (it may not work.)

cool massive dragon.
i didnt build it but i thaught it was so cool i needed to upload it so u guys can see it too
i dont remember who made it.

add whatever you want. it has cheats so you can also put it on survival.

This is TNT Run (in hardcore version!) a well known minecarft server minigame. But this is different- this is VERY hard. Up to 4 players in this game, there is only 1 floor, and that's it. So good luck!

(You may play in single player instead of 2-4, but it doesn't matter.)
Also, don't cheat after you fall in the void. When you re spawn, go to creative, turn invisible and spectate.

UPDATES: June 14th, 2013: Spawn Area Changed to higher point, due to players instantly dying when crossing under it.
