8 Areas

Time to play: 1-2 hours (depends on how much you fall off things)
Difficulty: Very easy (depends on how prone you are to falling off things)
Recommended # of Players: 1-2

The basic objective is to open the iron door in the spawn room. To do this you must complete each of the 8 areas branching off from the central room by pulling the lever at the end of each. Once you have completed all 8 areas, the door will open. You can see which areas you have and haven't completed by looking at which redstone lamps in the spawn room floor are lit up. Dark = Incomplete, Light = Complete.

Each of the 8 areas contains something different, from puzzles with minecarts to jumping across platforms high above the ground in a very dark room. Almost all of the areas rely on parkour/jumping.
