Survival 'peninsula'

Everyone has heard of survival Island right? Well I thought why give all the credit to islands when there are plenty of good peninsulas to survive on.
But darkskuller can't we just walk right onto the land the peninsula is connected to?
Well you could but that would ruin the fun. Also I may have placed some spawners to help influence you on not leaving the peninsula.
The wall isn't to keep you in, it's to keep them out...
Coords just in case you don't spawn in the right place: x -62 z 154
Some challenges:
Make a two story house that includes: glass (panes or blocks), wood (of some sort) and bricks.
Make a potato, carrot and wheat farm.
Get diamonds!
Find the dungeon and the scientist's chest.

Play on HARD mode for the optimal experience.

Please comment on anything I forgot to put, or suggestions!, I am leaving for Boston tomorrow so after tomorow answers to comments may be delayed.

Finally, my old account seems to have been deleted so guess who gets to start over! Good luck!
