floaty islands survival

welcome to my first survival map, floaty islands.

you are stranded in the flat lands, devoid of life and structures alike. you must survive using resources from the floaty islands. challenges:

make a cobble generator,
build a 3 story house,
make a wheat farm,
make a pumpkin farm,
make a melon farm,
make a full set of armor,
make a full set of diamond tools,
make a pig farm.

it probably won't be great, because it's my first survival map.

Additional Notes

this was made in minecraft 1.2, so don't come running to me if you have problems with invisible blocks and stuff. I did not use mods to make this, all the islands were made by me.
