[Surv] Time Bomb
How long can you keep Grandma's furnace burning?  If the fire goes out... kaboom!

A custom survival map by Albarel, smalecr@gmail.com

"Foreword"
This was an experiment inspired by Captain Sparklez recent "Redstone for Dummies" video.
I've never seen this mechanic used in a custom map.
The basic 'survival' part of this map is only going to be as difficult as any random seed.  However... there is a timer counting down in this map, and if the timer gets to zero, you lose.  You can add more time to the timer, but not diffuse it.


"The Story"
After completing countless adventures and amassing riches, you receive a letter from your Grandmother.  It seems she wrote the letter under duress.  She has been taken hostage in the basement of her cottage, by a man seeking revenge upon you.  You rush to her cottage to find it has been rigged with explosives with multiple triggers.  Attempting to disarm any of the bombs will set off the charges.


"Rules"
- Survive.  You can mine/craft/place any blocks you like.  And while you're doing that...
- Don't attempt to disarm the bombs, which means... 
- No digging under the house or through the walls, and...
- If the house explodes, you LOSE


"Maintaining the timer"
The house is rigged with 7 different triggers that all work on the same principle.  Things you should avoid doing;
 - Opening the cellar door
 - Taking the record out of the jukebox
 - Sleeping in Grandma's bed
 - Opening either of the doors between the bedroom and kitchen
 - Eating Grandma's cake
 - Letting the furnace fire go out.  Different materials burn at different rates.  You have to keep it stocked with a combustible as well as a raw material.  And don't forget to clear out the smelted item or the furnace may stop prematurely.

So that's it.  Very simple.  (how long can you resist seeing what happens if you do one of the above?)
