“Oh, chunk.” is a ‘challenge’ world, in the vein of Noobcrew's Skyblock Survival, or SethBling's SkyGrid.

There's one crucial difference: Skyblock and friends restrict only your resources, providing infinite space. “Oh, chunk” restricts both your resources and space. In Chunk, you try to play and survive in a single Minecraft level-chunk. 16×16 blocks. That's all you have to build in, and survive.

Good luck.

Playing

Currently, I'm not intending to set specific ‘challenges’ for Chunk players, à la Skyblock's. More than anything else, the primary goal of “Oh, chunk.” is to escape the Chunk into the Overworld.

There's only a few rules:

The first rule of Fight Club ... is to not spoil it for anyone else. Please, please preface any commentary you publish that might let other players in on the secrets of the map with some sort of spoiler-warning! This applies even if you're intentionally discussing solutions to the problems Chunk presents, or doing Let's Play-style coverage. (I've seen Skyblock ruined for altogether too many newcomers, by the viral nature of CaptainSparklez.)

But seriously, warn them to play it themselves, first!
No cheats or commands. (What's the point of a challenge-map, if you're not going to rise to the challenge, eh? Where's the fun in that?)
In a similar vein, no mods. Particularly, no SmartMoving, or anything that allows you to fit through 1×1 spaces; but nothing else is considered kosher, either. Play Chunk completely vanilla.

Those said, there's a few more notes I'd like to leave for the aspiring Chunker:

There is a way out;
That way out is not geographically hidden. You don't need to mine every single block you ever manage to work out a way to access, to find some sneakily-hidden hole over in the corner of the map. That's not fun, nor does it require much thought!
The map is designed to be played on Hardcore mode. Yes, that's scary, for those of you who've always shied away from that big bad Hardcore button; but give it a chance. As challenge-maps go, Chunk isn't a very long drawn-out one. If you do screw it up and die, it's much easier to start over than it is in Skyblock or SkyGrid and friends. Don't be afraid!

(That said, it's acceptable Chunking practice for the newcomer to occasionally manually copy their savefolder, and restore it after dying. This retains the desired hunger-mechanics and at least some death-penalty, without the over-extreme pain of starting over entirely from scratch. I call this “Hardishcore Mode.”

Also, it's reasonable to disable Hardcore after you escape, if you wish to continue playing your world, but aren't the type to enjoy that sort of pressure.)

About

Most of the most popular or interesting things I see in Minecraft are so large. I wanted to encourage compactness, and the development/furthering of various techniques for compact designs in this game. More compact farms, more compact spawners, more compact circuits, and more compact constructs of all sorts. Hence, this approach to restriction-challenges.

I'd eventually like this to be a map generator. Manually re-arranging things manually in MCEdit has been time-consuming, and burns me out quickly. Unfortunately, I fucking hate Java. Perhaps I can get one of you fine chaps to do it for me? ;)

As for the name ... I started playing Minecraft with my girlfriend. The night we began playing, we were quickly overridden by zombies, lost the (very little, in retrospect) that we'd managed to do, and got very fed-up very quickly. For weeks thereafter, we both exclusively played in Peaceful. Finally, when I decided to balls-up and try to take on Easy, and mobs, again, I titled the world we'd be playing in “Oh, fuck.” This map is intended to evoke a similar feeling. (That, and the entire game, or at least the first parts of it, are played in a single Minecraft ‘chunk.’)
