This is the Endless Sands adventure/puzzle map. What currently exists are the first first four sections of the Labyrinth portion of the Endless Sands map, as well as some of the sixth chapter of the map (City). It's not complete in any sense of the word, but feel free to play through it regardless.
I have written a walkthrough, and it's posted as 'Endless Sands Walkthrough' on fictionpress.

Have fun! Tell me if it works.

Update:
Looking around I found out that this is already larger than almost any maze ever built in Minecraft. Uhhh. Okay.
The floor space alone in the four enclosed sections of the Labyrinth so far total up to 228,290 blocks. If you add in the walls and airspace of the two maze sections that are designed at a constant level, it goes up to 1,064,860 blocks.
This literally might be the largest maze ever built in Minecraft. Whoops. That was not really my intention when I started making this, but... if it happens, it happens. I've still got plenty more sections to build! We'll see how it turns out in the end.

My Village,forever WIP!
Villages I've made:
-Desert Village(UPDATED!)
-Pyramid Stained Clay Village(HOT!)
-Savanna Village(NEW!)
-Plains Village

This map comes with a crater at where you spawn.Also a chest with 3 diamonds.There is a NPC village near to you.Contains huge dungeons and an End Portal to the South West (under the sea).Remember to watch out for Creepers in deep forest!

-I recommend using John Smith's texture pack for this map.

The current server my friends and I are playing. There are several canyons and lava pits dotted around.

This map was created with Server version 1.4.7 and seed -1175648186, regular biomes. We explored a fair amount of the server to expose some of the maps features.

We found:
- jungles
- swamps
- taigas
- oceans
- rivers
- deserts
- forests
- extreme hills
- and extreme hills versions of all the other biomes including taiga

This is a random map I made using World Painter.
There's not much to explore so it's mainly focused on survival and enjoying with your friends.

Spawn on edge of jungle, head to village which is on top of a ravine surrounded by horses, just over the ravine is a desert. also natural lakes and streams next to ravine.

This is a desert-themed map I have created. it is mainly parkour and logic, with miscellaneous skill challenges thrown in. It is relatively short, as it comprises of 15 challenges/rooms. This map spans a range of difficulties, and is also fine to be used as a multiplayer world.

Gameplay:
Difficulty = normal
Follow the instructions and prompts on signs and in books.

Please give me suggestions/tell me what you think (my email is [email removed]) as this is my first upload and I am keen for feedback.
