New Gameplay Style: House Survival

[The Devious Chicken]

House Survival:

What it is: You start in a small, basic house, with a chest full of Iron Ore, Coal, Sticks, and a random peice of Leather Armor, a Furnace and a Crafting Table. You have all day to prepare for the night, when it is required to fight outside.
What will spawn:
Overworld:
Nights 1-5: Zombies and Skeletons
Nights 6-10: Zombies and Creepers
Nights11-15: Zombie Pigmen and Creepers
Nights 16-20: Zombie Pigmen and Ghasts
Nights 21-25: Ghasts and Endermen
Nights 26-30: Endermen Only.
Night 31: End Portal to The End
The End:
Night ?: Endermen and Ender Dragon
Cavern:
*Read Overworld*
What will drop:
Zombies: Rotten Flesh and Leather
Skeletal Archers: Bows, Bones and Arrows.
Creeper: TNT, Redstone
Zombie Pigmen: Golden Ingots, Golden Sword
Ghasts: Flame Orbs
Endermen: Eye of Ender
Ender Dragon: Dragon Egg
How to win:
Survive until the 31st night, and defeat the Ender Dragon.
Trivia:
1. There IS a Hunger Bar, but Pigs spawn, so don't worry.
2. Unlike most created worlds, this one has a finite end, so you will be basically fighting in an arena.
3. Once its night, the chest will be locked, the Furnace and Crafting table will be unusable and you will not be able to re-enter the house until the morning.
4. The Morning goes on for 5 minutes, but if you think your ready, you can sleep in the bed to sleep until night.
Bonus Challenges:
- Defeat the Ender Dragon without getting damaged once
- Survive until 31st night only using Leather/no armor.
- Kill an Enderman without getting hit once.

Additional Stuff
1. Your house is automatically made.
2. This world is Finite.
3. This world cannot be edited in any way, other then Creeper explosions, you can't add or remove blocks.

No challenge at all unless we're not allowed to build little pillars to LOS the skeletons with, at which point the only challenging night would be the first one. Skeletons are the most dangerous monsters in the game.

Sounds a bit like a survival map I played a while back (read: last year), only that was confined to a rather large, but limited, arena-esque mansion. Certainly could be interesting. I assume you would have an enchanting table so players could make use of whatever experience they accumulate over the course of the map?

The skeletons would suck without and cover.

The skeletons would suck without and cover.

Just build little pillars around the house, or just build a house around the house. Add a doorway (don't even need a door), lure the skeletons to the doorway, left-click until your finger gets tired.
